Step 1 Begin with the Work-Energy Theorem. DKFdrdisplaystyle Delta Kint mathbf F cdot mathrm d mathbf r Step 3 Rewrite force in terms of velocity. Kinetic Energy K 12 m v2 12 m2 v2m 12 p2m p2 2m.

Lets take an example.

Note that mass is a scalar and can therefore be factored out. The dot product can then be expressed as.
