Question

When an arrow is shot from its bow, it has kinetic energy. From where does it get its kinetic energy?

Answer 1

Hint:When an object is made to fall from a high point, its potential energy is converted into kinetic energy of the motion. Arrow held in a stretched string will contain stored energy. So we have to use the concept; we will get answers to this type of question.

Complete step by step answer:
The energy stored as a result of applying a form to deform an elastic body is termed as Elastic potential.

The energy will be retained until the force is removed and the spring reaches its original shape.

Potential energy is stored energy by virtue of its location or configuration. When the body is left to itself it gives away this stored energy as kinetic energy.

The energy possessed by a body by the virtue of its motion is termed as Kinetic energy.

It is determined by the amount of work that the body can do against a restraining force action on the body before it comes to rest.

A bow with its string stretched gains potential energy due to change in its shape.

To shoot an arrow, the string has to be released.

The kinetic energy is converted by the potential energy of the bow.

Therefore, potential energy is converted into the kinetic energy.

Note:Potential energy is the energy stored in the body when deformed. When it retains back to its original state the potential energy stored in the body gets converted to kinetic energy.
