## P4 Formula

Average Speed - Distance travelled / time taken

Change of Momentum - Force x Time for which it acts

Momentum - Mass x Velocity

Velocity - Momentum / Mass

Work done - Force x Distance moved in direction of force

Gravitational Potential Energy - Weight x Vertical height differance

Kenetic Energy - 1/2 x Mass x (Velocity)x(Velocity) - [I mean squared but the         computer wont let me do the little 2]
