Question

The point of minimum kinetic energy in case of oscillating pendulum is ____________ position. (extreme or mean).

Answer 1

1. The oscillating pendulum possesses potential energy and kinetic energy.
2. When the pendulum oscillates, the total energy at all points remains the same if resistance force such as air resistance is absent.
3. When the bob reaches the extreme end during oscillation, the potential energy is maximum.
4. When it moves towards the mean position, the potential energy decreases and converts into kinetic energy.
5. So, the kinetic energy is minimum in the extreme position.

Hence, the answer is extreme.
