A ball moving horizontally along the road has stopped due to friction. What happened with the potential energy?

The potential energy is determined by the formula

E = m * g * h,


E – energy;

m is the mass;

g is the acceleration of gravity;

h – height.

Since the ball was moving horizontally, its height did not change. Therefore, at any constant values of m and g, the Energy remained unchanged.

Answer: the potential energy of the ball has not changed.
