A stone falls from the roof of the garage. How does its speed and potential energy change relative to the Earth during the fall of a stone? Why does its speed increase?
Epotential = mgh. As the stone approaches the ground, the height h decreases, therefore, the potential energy itself decreases. And since it decreases, the kinetic energy (Ek. = (Mv ^ 2) / 2), on the contrary, increases, and it follows that the speed also increases
Answer: speed increases, potential energy decreases
