Resistance force

In physics, resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pounds-force.

For an balls, (frictionless) mechanism in which no energy is lost, resistance force obeys the equation.

R × D R = E × D E

where:

R equals resistance force D_R equals resistance distance E equals effort force D_E equals effort distance

Resistance force is used to calculate the work output using the following equation:

W o r k o u t p u t = R × D R
