Question

Write SHORT examples of Gravitational potential energy and Elastic energy

Answer 1

Dropping a bouncy ball and stretching a rubber ban.

Answer 2

Answer:

Examples of a gravitational potential energy are; a flying helicopter, objects thrown up  and examples of elastic energy are; an archers stretched bow,  a stretched rubber band

Explanation:

We will start by giving a short definition of the two terminologies

Gravitational potential energy is the energy an object possess as a result of its position above the surface of the earth.

$E_{P}$ = mgh

where m = mass     g = gravitational field strength      h= height      and $E_{P}$ =gravitational potential energy

Examples are; a flying helicopter, objects thrown up

Elastic energy: This occurs as a result of stretching, compressing or  deforming of an object impermanently.

$E_{e}$  =  $\frac{1}{2}$ ke²

where k = spring constant       e=extension   and $E_{e}$ =Elastic potential energy

           

examples of elastic energy are; an archers stretched bow,  a stretched rubber band
