Show that the units of kinetic energy and of gravitational potential energy are the same.

Explanation:

We have to first obtain the unit of each of the individual energies.

Kinetic Energy

E = 1/2 mv²

The units are;

mass, m = Kg

Velocity, v = m⋅s−1

This means that;

E = Kg * (m⋅s−1)²

E = kg m² / s²

Gravitational Potential Energy

Pe = mgh

The units are;

mass, m = Kg

acceleration due to gravity, g = m/s²

height, h = m

E = Kg * m/s² * m

E = kg m² / s²

Comparing both units, we can tell that they are the same.
