Question

An arrow is fired at a target on a high wall. Which statement correctly describes the change in the energy of the arrow as it moves toward the target?
The potential energy and kinetic energy remain the same.
The potential energy decreases as kinetic energy increases.
The kinetic energy decreases as potential energy increases.
The kinetic energy remains at zero, but potential energy increases.

Answer 1

Answer : Option C) The kinetic energy decreases as potential energy increases.

Explanation : As the target is fired high on the wall, the change in the energy that is observed as the arrow moves towards the target is kinetic energy starts to decrease as the arrow reaches nearer towards the target and the potential energy is observed to increase. So, in short the energy transformation is from kinetic energy from a moving arrow to potential energy when the arrow hits the target.

Answer 2

The kinetic energy decreases as potential energy increases.(C)
