Work = Force × Distance
W = F × d
Use the force component in the direction of motion
W = Fd cos(θ)
F = force
d = distance moved
θ = angle between force and displacement
Unit of work: joule (J)
1 J = 1 N·m
If force and motion are in the same direction, W = Fd
If force is opposite the motion, work is negative
If there is no displacement, work = 0
