Question

A stone rolls down an inclined plane. Midway during the motion, the stone has

• A. only kinetic energy
• B. only potential energy
• C. both potential and kinetic energy
• D. neither potential nor kinetic energy

Answer 1

The correct option is C

both potential and kinetic energy

1. The stone in the midway of an inclined plane is at a certain height and since it is moving it also has velocity associated with it.
2. Since it is at a certain height it possesses potential energy.
3. Since it has some velocity it also possesses kinetic energy.

Hence option(C) is correct.
