Resistance force: Meaning (information, definition, explanation, facts)

In physics, resistance force is the force which an effort force must overcome in order to do work on an object.

Resistance force is a component in the following equation,

R × D_R = E × D_E

where R equals resistance force, D_R equals resistance distance, E equals effort force, and D_E equals effort distance.

Resistance force is also a component in the following equation,

Work output = R × D_R

where R equals resistance force and D_R equals resistance distance.

Resistance force, like most other forces, is measured in the U.S. customary unit, the pound, or the Metric unit, the newton.
