Question

An archer stretches the string of a bow causing to bend. When the bow straighten, the string also comes back to the original place pushes the arrow out from the bow. Identify where force is being used to change the shape of an object. Also identify the object on which work is being done. Give reasons for your answer

Answer 1

As the archer streches the string the potential energy is stored in the bow due to its change in configuration and when the archer shots the arrorw the potential energy of the bow is transferred to the arrow  in the form of kinetic energy which gives it the tendency to do work and it moves with a fast velocity .

Answer 2

Here is your detailed answer:

Explanation:

You see, the archer utilizes mechanical energy in stretching the string of the bow.

This mechanical energy is then converted into the potential energy when the string is pulled backwards, ready to be fired.

When the archer shots the arrow, the potential energy then transforms into kinetic energy when the arrow is shot forward.
