m^2 1 Joule = 1 kg * ----- s^2One Joule is a very small amount of energy.
Work = (force) * (distance parallel to force)or, in general
Work = (force) * (displacement) * cos(theta)where theta is the angle between the direction of the force and the displacement.
KE = 0.5 * (mass) * (speed)^2
work done on object = change in kinetic energy = KE(final) - KE(initial) 2 2 = 0.5 * M * v - 0.5 * M * v f i
