Question

An archer draws back the string of his bow and fires an arrow toward a target. What converts the potential energy of the bow into the kinetic energy of the arrow

Force
Work
Momentum
Time

Answer 1

Force

Step-by-step explanation:

Mechanical energy, which refers to the energy of an object due to motion or position, is of two types viz: kinetic energy and potential energy. Kinetic energy is the energy of an object in motion while potential energy is the energy of an object at rest. These two (kinetic and potential) makes up the mechanical energy. Kinetic energy and potential energy are interconvertible.

In this question involving a bow, the bow is at a state of rest when the string is unpulled i.e. possess potential energy. It becomes kinetic energy when the archer pulls the string in order for the arrow to move in a particular direction. FORCE is what is required to pull the string, hence, force is what changes the potential energy of that bow to kinetic energy.
