When the unit of force and length are both doubled, what happens to the unit of energy?
When the units of force and length are doubled, the unit of unit energy grows fourfold.
The following is the relationship between energy, force, and distance:
Force multiplied by distance equals energy.
N and m are the units of force and distance, respectively.
As a result, E = N x m
As a result, E = 2 N x 2 m
As a result, E = 4Nm.
