A body is falling from a height h. After it has fallen a height h/2 , it will possess:
Correct answer: C. Half potential and half kinetic energy
- A. Only potential energy
- B. Only kinetic energy
- C. Half potential and half kinetic energy
- D. More kinetic and less potential energy
Explanation
P.E = mghP.E = mgh/2 [h' = h/2]P.E' = P.E/2So at h/2. body has half P.E and half K.E.

About Potential Energy
Potential energy is energy stored because of position or configuration, including gravitational potential energy near Earth's surface and elastic energy in a stretched or compressed spring. Questions use changes in potential energy and conservation of mechanical energy, while distinguishing a chosen reference level from an absolute zero of energy.
