There's also this thing called conservation of momentum and impulse. The more massive object is less likely to experience changes in direction or speed. Why do you think you can throw a ball at a brick wall and have the wall not move despite it having no kinetic energy? Now, I realize real world physics does not apply because this is a video game, especially one made by PGI, but seriously...know your physics.
Okay, here's your math for a 35 tonne firestarter running at 150 km/h trying to move a 100 tonne atlas standing still on concrete on Earth.
Resistance from friction
n = coefficient of friction * mass * gravity
n = 1 * 100 tonnes * 1000 kg/tonne * 9.81 m/s^2
n = 981,000 kg*m/s^2 (aka Newtons)
Kinetic energy
e = 1/2 * 35 tonnes * 1000 kg/tonne * (41.66 m/s)^2 <-- 150 km/h = 41.66 m/s
e = 30,372,223 kg*m^2/s^2 (aka Joules)
Joules / Newtons = Meters
30, 372, 223 kg*m^2/s^2 / 981,000 kg*m/s^2 = 30.96 m
So that firestarter is going to make that Atlas move 31m when it hits it. An Atlas is about 16m tall? In relative terms, imagine being hit so hard you get tossed 12 feet back. It's quite a fair distance.
Edit: added some details
