Question

I’m making a game in which I’m creating an animation system that speeds up based on the velocity of the character.

The problem is this won’t work for the instance of a treadmill.

I do not have the speed of the treadmill, but I do have the force of the friction between the treadmill and the character.

I’m trying to determine if a force is making a difference. Knowing Only the forces that are being applied to an object, its weight, and its velocity, how would you determine if a single force is making a difference in it’s velocity, and if so, how much?

Answer 1

F = m*a

a = d/dt v

With finite differences:

a = (v2-v1)/dt

And therefore the relationship:

F = m * (v2-v1)/dt

I hope, this helps 🙂
