A ball is projected into the air with 100 J of kinetic energy which is transformed to gravitational potential energy at the top of its trajectory. When it returns to its original level after encountering air resistance, its kinetic energy is

Question

Quizplus · Accepted Answer

Due to air resistance, some of the ball's energy is converted into other forms, such as heat, resulting in less kinetic energy when it returns to its original level compared to when it was projected.
