A ball moving horizontally along the road has stopped due to friction. What happened with the potential energy?
July 26, 2021 | education
| The potential energy is determined by the formula
E = m * g * h,
where
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.
