I'm new to many forces, such as gravity and friction, and I don't really know how they work. I'm trying to simulate a ball bouncing with a program, and it travels at a constant speed horizontally. I can calculate the friction on it (in Newtons of force).
However, since the ball is traveling at a constant speed horizontally, there is no acceleration. Therefore, since
F = MA, if
A = 0, then there is no force behind it. This makes sense because of Newton's first law: if an object is in motion, then it will stay in motion, unless another force acts upon it - in this case, that force is friction.
I know the speed, mass, density, and other properties of the ball. I know the force of the friction. But I don't know how much the friction will slow down the ball.
Is there an equation, or easy way to figure out how much to reduce the speed of the ball?
As @Luke said in his comment,
F = MA can be rearranged to solve for the acceleration (or deceleration) of the ball given the force and the mass.
