Neglecting air resistance, when you toss a stone straight up in the air from Earth's surface, which of the following statements is true for the upward motion of the stone.

Question

Quizplus · Accepted Answer

Neglecting air resistance, the stone initially has only gravitational potential energy. As the stone moves upwards, its speed decreases and eventually becomes zero at the highest point. At this point, the stone has no kinetic energy, but its height above the ground is maximum, giving it maximum gravitational potential energy. Therefore, the stone's kinetic energy decreases while its gravitational potential energy increases during the upward motion.
