Ok. I'll be putting common feats here over time. Including getting hit by a train, falling off an average building, and others
Getting hit by a train
Ok. So, we are gonna do basic KE for trains. Let's go over a few I know of
So a single cart in a freight train is around 30 tons when empty. And can carry up to 100 tons more. Which is a total of 130 if it's full. I also found a general restriction of more than 180 carts in the US. So that's our highest end. And for an average. I had a hard time finding anything for a general average. But we are gonna put 50 for our midish end. And then 10 carts for our low end. As that's the typical area for trains. I also found they can go up to 60 MPH. So easy From there
Empty Carts, 10 Carts
Low Low end: KE = 97,899,904 Joules of energy. Small building level
Full cart, 10 Carts
Low Mid end: KE = 424,232,916 Joules of energy. Small Building level
Empty Carts, 50 Carts
Mid Low end: KE = 489,499,519 Joules of energy. Small Building level
Full Carts, 50 Carts
Mid Mid end: KE = 2,447,497,594 Joules of energy. Building level
Empty Carts, 150 Carts
High low end: KE = 1,468,498,577 Joules of energy. Building level
Full Carts, 150 Carts
High mid end: KE = 6,363,493,745 Joules of energy. Building level+
This was an easier one. These trains can weight between 211 tons to 300 tons. And they went generally in the same 60 MPH area. So. Let's KE this
Low end: KE = 68,856,266 Joules of energy. Small Building level
Mid end: KE = 81,909,586 Joules of energy. Small Building level
High end: KE = 97,899,904 Joules of energy. Small Building level
Looking up the weight. I find the average is a solid 715 tons for a bullet train. And a speed of 162 to 186 MPH. Simple KE.
Low end : KE = 416,319,341 Joules of energy. Small Building level
Mid end: KE = 496,948,783 Joules of energy. Small Building level
High end: KE = 548,810,544 Joules of energy. Small building level
Falling off sorta high buildings
Falling off a building Attempt 1
Falling off of buildings
Ok. So here's a feat you'll often see. Falling off of buildings. We are talking about average buildings. 1 story. 2 story. 3 story. So let us take a gander.
Assuming the weight to be around 200 pounds for an Average American. And every story is about 14 feet
As well. Using this calculator
200lb falling 14 feet with normal air resistance gets 20.3 MPH
3,735.516 Joules of energy or 3.735516 Kilojoules. Street level
200lb falling at 28 feet with normal air resistance gets 28.6 MPH
7,414.65 Joules of energy or 7.41465 Kilojoules. Street level+
200lb falling at 42 feet with normal air resistance gets 34.8 MPH
10,977.84 Joules of energy or 10.97784 Kilojoules. Street level+
200lb falling at 56 feet with normal air resistance gets 40 MPH
14,503.7 Joules of energy or 14.5037 Kilojoules. Street level+
200lb falling at 70 feet with normal air resistance gets 44.5 MPH
17,950.58 Joules of energy or 17.95058 Kilojoules. Wall level
200lb falling at 84 feet with normal air resistance gets 48.5 MPH.
21,322.7 Joules of energy or 21.3227 Kilojoules. Wall level

24,511.24 Joules of energy or 24.51124 Kilojoules. Wall level
200lb falling at 112 feet with normal air resistance gets 55.3 MPH
27,721 Joules of energy or 27.721 Kilojoules. Wall level
200lb falling at 126 feet with normal air resistance gets 58.4 MPH
30,916.06 Joules of energy or 30.91606 Kilojoules. Wall level
200lb falling at 140 feet with normal air resistance gets 61.2 MPH
33,951.7 Joules of energy or 33.9517 Kilojoules. Wall level
Falling of a building Attempt 2
So I was told another way to calc falling. Multiple the weight by the height and then convert foot-pounds to joules.
200lb * 14 feet = 2,800 Footpounds or 3796.29 Joules. Street level
200lb * 28 feet = 5,600 Footpounds or 7592.581 Joules. Street level+
200lb * 42 feet = 8,400 Footpounds or 11388.87 Joules. Street level+
200lb * 56 feet = 11,200 Footpounds or 15185.161 Joules. Wall level
200lb * 70 feet = 14,000 Footpounds or 18981.451 Joules. Wall level
200lb * 84 feet = 16,800 Footpounds or 22777.742 Joules. Wall level
200lb * 98 feet = 19,600 Footpounds or 26574.032 Joules. Wall level
200lb * 112 feet = 22,400 Footpounds or 30370.322 Joules. Wall level
200lb * 126 feet = 25,200 Footpounds or 34166.612 Joules. Wall level
200lb * 140 feet = 28,000 Footpounds or 37962.903 Joules. Wall level
200lb * 154 feet = 30,800 Footpounds or 41759.193 Joules. Wall level
200 * 168 feet = 33,600 Footpounds or 45555.483 Joules. Wall level
Vaporizing a Car
Ok. I used an average car to get the measurements I got from here for the amount of Material. And I used what Vaporizing values already existed. And did the ones that didn't that I could find out
Starting with getting the Vap values for ones that didn't exist (to my knowledge)
Vaporizing Aluminum and Copper
One cubic centimeter of aluminum would have a mass of 2.7 grams per cubic centimeter
it has a boiling point of 2519 Celsius, a heat of fusion of 10.79 kJ/mol. a heat of vaporization of 293.4 Joules/mol and a molar heat capacity of 24.3 J/(mol*C)
Using the molar mass of Aluminum (26.982 g/mol), we convert the heat of fusion, heat of vaporization and molar heat capacity
10.79 kJ/mol * 1000 J/kJ * 1/26.982 mol/g
293.4 kJ/mol * 1000 J/kJ * 1/26.982 mol/g
Using the specific heat equation, we find the energy change to be (assuming room temperature) = (2.7g) (0.0243 J/gram*C)(2519 -20) = 163.95939 Joules.
Using the latent heat equation (as linked above as well), we find the other energy change to be = (399.896227114 J/g)(2.7g) + (10873.915944 J/g)(2.7 g) = 30,439.292862 Joules
And after the last hit of combining, we get a total vaporization value of 30603.252252 J/cc
One cubic centimeter of Copper would have a mass of 8.96 grams per cubic centimeter
it has a boiling point of 2927 Celsius, a heat of fusion of 0.38 J/g K kJ/mol. a heat of vaporization of 300.3 kJ/mol. and a molar heat capacity of 24.5 J/(mol*C)
Using the molar mass of Copper (63.546 g/mol), we convert the heat of fusion, heat of vaporization and molar heat capacity
0.38 kJ/mol * 1000 J/kJ * 1/63.546 mol/g
300.3 kJ/mol * 1000 J/kJ * 1/63.546 mol/g
Using the specific heat equation, we find the energy change to be (assuming room temperature) = (8.96) (0.0245 J/gram*C)(2927 -20) = 638.14464 Joules
Using the latent heat equation (as linked above as well), we find the other energy change to be = (5.97992005791 J/g)(8.96) + (4725.71050892 J/g)(8.96 g) = 42395.9462436 joules
And after the last hit of combining, we get a total vaporization value of 43034.8924872 J/cc
Vaporizing an entire car
Now that's done. We shall work on getting the Joules of energy from Vaporizing the car with the formulas we have.
Steel = 113,924.0506 * 71353.79 j/cc = 8,128,912,782.46 joules
Aluminum = 66,694.81481 * 30603.252252 = 2041078241.53 Joules
Copper = 2,480.580357 * 43034.8924872 = 106,751,508.969 joules
For Cast Iron
Cast Iron = 18,051.73151 * 71,353.79 = 1,288,059,459.3
Here's where I couldn't get any Vaporize values due to them lacking certain things to find Vaporizing. So Unless Glass, Plastic, Natural Rubber, and Synethic Rubber get Vap Values. Nothing much I can do. Taking what we do have though.
8,128,912,782.46 + 2,041,078,241.53 + 106,751,508.969 + 1,288,059,459.3 = 11,564,801,992.259 Joules of energy or 2.764054013446223923 Tons of TNT. Large Building level
This is a fairly good Lowball since we weren't able to take into consideration the Rubbers, Platstic, and Glass. (If ever found out. This will be updated)
Glass = 9,071.84 * 1000 = 9,071,840 joules of energy
Plastic = 81,890.1566 * 38.7 = 31,691,49.06042 joules of energy
Natural Rubber = 6,902.486957 * 1 = 6,902.486957 joules of energy
Synthetic Rubber = 13239.9827 * 4.285714286 = 56742.7830038 joules of energy
8,128,912,782.46 + 2,041,078,241.53 + 106,751,508.969 + 1,288,059,459.3 + 9,071,840 + 3,169,149.06042 + 6,902.486957 + 56,742.7830038
11,577,106,626.6 joules of energy. Large Building
Changing Clothes fast
Here's a feat I've seen a few people do which people claim is impressive. Switching a set of clothes they are wearing to another set. This is a comedic feat that often takes roughly 1 second to pull off. I'll do as far as 2 seconds. Cause from there it loses its speed potential. You'll see why. It's not as impressive as you think.
So. How will we do this? We will consider the movement your arms would have to make while changing clothes. This will get the bet result as your arms docthe most movement when changing a set of clothes. We will first do average clothes. A shirt, pants, socks, and shoes.
We will assume our person to be roughly 6 foot.
Assuming they remove this from top to bottom and in the fastest manor. We start with the shirt. Which we remove it by pulling it over our heads. Meaning our arm is going as far up as it can go likely. For a 6 foot person. Their arm can about land between 1.5 to 2 feet from elbow to fingertip. To make it easier. We will assume the better end of 2 feet. Or 24 inches
So the actions you have to take off the shirt is to pull it over our heads and it's off. This means the arms should travel roughly 24 inches when lifting to take it off. And 24 more inches to get back its normal place. So roughly 48 inches. Maybe a bit more or less depending on the type and how someone may change their shirt. But this is a decent average
Shirt = 48 inches
So first. We have to assume you unzip them as most pants come with a zipper. The average zipper is about as long as your longest finger. And may be a bit longer or shorter. But the zipper should at least hit 4 inches. We save this for later
Now the action of taking off pants. Average length for a leg hits 31.8898 inches. So your arm and body would have to travel the entire length of your leg to take them off. Now this is where shoes and socks come in. Assuming you take them off here rather than going all the way back up just to go back down. To take off your shoes. You'll have to go the length of your own foot to pull them off assuming they aren't easy slip off shoes. A foot on average is 12 inches. And you have 2 feet. And do this for socks as well. So 12 times 2 times 2. 48 inches for your shoes and socks. Then you go back up the distance of your legs. But that's under Pants. Since you travel 31.8898 inches twice. That's 63.7796 inches. And then we add 4 to that for the zipper
Pants = 67.7796 inches
Shoes = 48 inches
Socks = 48 inches
67.7796 + 48 + 48
That's a grand total of 163.7796 Inches.
But wait. Since this also includes putting on the clothes too. We double it to 327.5592 inches. And since we would likely have to both unzip and result when putting on pants. We add 4 more to consider the extra zipping process that putting them on would provide. And a grand total of 331.5592 Inches. Or 27.629933333 feet.
Now for the timeframe.
1 second = 18.8385909088636 MPH or 8.421603679898383987 MPS. Athletic Human
2 second = 9.419295454431818 MPH or 4.2108018399491999872 MPS. Below Average Human
Yea. Not nearly as impressive. And definitely not Subsonic like I've seen claimed before. Now this won't be entirely accurate since peoples size tend to vary. But this gives the general idea that this feat doesn't offer much at all.
Breaking a brick
Breaking a brick
Here's a good one. Breaking bricks. Ill show the math for breaking a single one. And this can give reference to if someone breaks multiple. Simply multiple it by the amount of bricks
A normal Brick
A normal brick is 22.5 cm x 11.25 cm x 7.5 cm (length x depth x height). So very easy to get the CC.
1898.4375 • 3.49375 = 6,632.666015625 Joules. Street level
Pretty good I'll say. This is per brick. So breaking through brick walls is a pretty good feat.
M1 Abram Tank Destruction
So a feat I’ve seen a few times is destruction of a tank. I’ll be doing the Frag, V Frag, Pulverize, melting, and vaping it. So let’s do this
Weight Of Tank
First, we need to get the Cubic Centimeter of the Tank. I was told this method. Considering it to be an M1 Abrams Tank. We will use the weight of 65,000 KG
Mass / Density to get the volume then convert to cubic centimeters using the found volume.
Mass: 71.650235 metric tons (65,000 kg) of steel
Density: 7700 kg/m
Volume = 65,000 / 7700 = 8.38709677419 m^3
0.155 m^3 = 8,441,558.44156 cm^3
Ok. Now that’s over. Let’s take this to the calc
The Fragging for steel is 208 J/CC
8,441,558.44156 * 208 = 1,755,844,155.84448 Joules of energy. Or 0.41965682501063100718 Tons of TNT. Building level
V Frag end
The V Frag of steel takes 568.5 J/CC
8,441,558.44156 * 568.5 = 4,799,025,974.02686 Joules of energy. Or 1.1469947356660756821 Tons of TNT. Building level+
The pulverizing for steel is 310-1000 J/CC. We will do a low and high end.
Lower Pulverize end
8,441,558.44156 * 310 = 2,616,883,116.8836 Joules. Or 0.62545007573699817893 Tons of TNT. Building level
Higher Pulverize end
8,441,558.44156 * 1000 = 8,441,558,441.56 Joules. Or 2.017580889474187344 Tons of TNT. Large Building Level
To melt steel that’s 7309.87 J/CC.
8,441,558.44156 * 7309.87 = 61,706,694,805.2062 Joules. Or 14.748254016540679245 Tons of TNT. City Block level
it takes 60117.42 J/CC to Vap steel.
8,441,558.44156 * 60117.42 J/cc = 507,484,714,285.808 Joules. Or 121.29175771649330784 Tons of TNT. Multi City Block
Frag end = 1,755,844,155.84448 Joules of energy. Or 0.41965682501063100718 Tons of TNT
V Frag end = 4,799,025,974.02686 Joules of energy. Or 1.1469947356660756821 Tons of TNT. Building level+
Pulverizing Lower end = 2,616,883,116.8836 Joules. Or 0.62545007573699817893 Tons of TNT. Building level
Pulverizing Higher end = 8,441,558.44156 * 1000 = 8,441,558,441.56 Joules. Or 2.017580889474187344 Tons of TNT. Large Building Level
Melting End = 61,706,694,805.2062 Joules. Or 14.748254016540679245 Tons of TNT. City Block level
Vaporizing End = 507,484,714,285.808 Joules. Or 121.29175771649330784 Tons of TNT. Multi City Block
Some nice numbers. About what you would expect from a tank destruction
So, we are simply looking at destroying a human body without vaporizing it. We will do Frag and Pulverize. (I don’t see any numbers usable for V Frag of a human)
Human body CC is 95,000
To Frag a human is 4.4 J/CC
95,000 * 4.4
418,000 Joules. Wall level
To Pulverize a human is 12.9 J/CC
95,000 * 12.9
1,225,500 Joules. Wall level
