Even the first velocity value is 0.396 cm/s and is absolutely far from the expected value 1.25cm/s velocity change after one shot of force = (1N-0.5N)*0.025s/1kg = 0.0125m/s = 1.25cm/sīut the results are strange - velocity is not only at x axis, and there even ticks where the x velocity is negative as shown in the snapshot.The change of velocity after the force shot should be: the kinetic frictional force should be then = 0.025 * 20N = 0.5N.Second experiment - friction value = 0.025Īt this time, the expected kinetic frictional force should be: velocity change after one shot of force = 1N*0.025s/1kg = 0.025m/s = 2.5cm/s.Gravity = -2000cm/s^2 (just in order to have nice numbers). FPS = fix 40fps (so tick time step = 0.025s).I set a physical material with zero friction for both, a floor and a cube, then add one shot of force of 1N to the cube within axis x: I did a very simple test for moving a cube over a floor with some friction, but got values that are not fit to the simple physics equation. I’m trying to get realistic results values in order to build some simulation - I don’t need real time simulation, thus, I would like to use UE4 with a good physics calculations even if it takes cpu time. But it may be interesting also for the forum. I tried to ask this question also in UE4 Answerhub, but lastly had problem with “question need moderator approval”.
