Question

Before a ball rolls down a hill, it has gravitational potential energy. Before a rubber ball bounces away from a surface, it has elastic potential energy.
From the list below, select the type of potential energy that allows you to throw a ball.

A.
elastic potential energy
B.
chemical potential energy
C.
gravitational potential energy
D.
human potential energy

Answer 1

Answer:

chemical potential energy

Explanation:

study island

Answer 2

Answer:

human potential energy

Explanation:

It is given that, before a ball rolls down a hill, it has gravitational potential energy.

Before a rubber ball bounces away from a surface, it has elastic potential energy.  

Human potential energy allows us to throw a ball. While throwing a ball, we have to apply some force by our muscles in order to done some work.Also, we know that the capacity to do work is called energy.

Hence, the correct option is (D) " human potential energy ".
