Question

What is the potential energy of the ball as it is half way through the fall, 20 meters high?

Answer 1

Explanation:

Given parameters:

height of the fall = 20m,

   given that the body is half-way through the fall, it is at $\frac{1}{2}$ x 20m above  the ground = 10m

Unknown:

Potential energy = ?

Solution:

The potential energy of a body is the energy due to the position of a body. It the energy at rest.

It is expressed as:

Potential energy = mgh

Where m is the mass of the body

            g is the acceleration due to gravity = 9.8m/s²

            h is the height of the body

input the variables;

  Potential energy = m x 9.8 x 10 = 98m

Since the mass is not provided, just input it.

 Also the unit of energy is Joules, J.
