# Work

Written by Jerry Ratzlaff. Posted in Properties

Work is the overcoming of resistance through space and is the measure of force x distance. Since the unit of force is a pound and the unit of distance is a foot, the product of a foot by a pound is a unit of work. This is expressed in ''foot pounds'' or ''Newton meters'."

Energy is the capacity of doing work and comes in many forms such as kinetic energy (KE) and potential energy (PE)

## formula

$$W = F d$$

$$W = F d cos \theta$$

Where:

$$W$$ = work

$$F$$ = force

$$d$$ = distance

$$\theta$$ = the angle between the force vector F and the displacement vector d

Solve for:

$$F = \frac {W}{d}$$

$$d = \frac {W}{F}$$
