This calc was 100% fully made by Red Angel
GoW needs moar calcs
So I figured I might as well try this out
Ares was about as tall as the suicide bluffs during the whole fight, which are about 1000 ft or so
Ares = 47 pixels/304 meters
Mountains height = 220 pixels/1422 meters
Mountains width = 62 pixels/401 meters
Distance Crossed = 132 pixels/854 meters
Timeframe = 1 second
It should be noted they moved from 1/2 to 2/3 to 3/3 of their width in a single frame. Frame rate is 30 fps (info courtesy of Derpaholic)
Velocity low end = 6015 m/s or Mach 17.68
Velocity mid end = 8019 m/s or Mach 23.57
Velocity high end = 12030 m/s or Mach 35.35
Now for the weight of the mountains
To measure volume, courtesy of this handy tool, and enter 200.5 as the radius and 1422 as the height gives us a result of 59,886,886.71 m^3 and it assuming it's made of granite
Volume = 59,886,886.71 m^3
Mass = 161,155,612,136.61 kg or 177,643,654.1 tons
Trying to find out how to raise mountains (as in creating a mountain out of the earth, will just use the KE formula as dartg suggested)
Low end
KE=0.5*m*v^2
0.5*161,155,612,136.61*6015^2
2.92 exajoules or 696.78 megatons
However since he raised 4, multiplying it by 4 will do
696.78*4 = 2.79 gigatons
Mid end
0.5*161,155,612,136.61*8019^2
5.18 exajoules or 1.24 gigaton
1.24*4 = 4.95 gigatons
High end
0.5*161,155,612,136.61*12030^2
11.66 exajoules or 2.79 gigatons
2.79*4 = 11.15 gigatons
So small island level+ to island level+ Ares. You could also powerscale the other gods off this (such as Hades, Poseidon and definitely Zeus and the Titans too), and Ares' death explosion should be at least as powerful as this, which Kratos tanked so, yeah
Still, guess GoW gods are now Bleach soloing material
Final tally
Moving mountain = 696.78 megatons | 1.24 gigaton | 2.79 gigatons
All 4 combined = 2.79 gigatons | 4.95 gigatons | 11.15 gigatons
Key: Low end | Mid end | High end
