KINETIC AND POTENTIAL ENERGY WORKSHEET Name:________________________ Determine whether the objects in the following problems have kinetic or potential energy. Then choose the correct formula to use: KE= 1/2 m v2 PE = mass x gravitational acceleration (10 m/s2) x height OR Weight X Height Energy= joules Weight= Newton Mass= kilograms Velocity= m/s Gravitational acceleration= (9.8 m/s2) 1.
