CALCULATIONS - Weight = mass x gravitational field strength
W=mxg
- gravitational potential energy = mass x gravitational field strength x height
Ep = m x g x h
-kinetic energy = 0.5 x mass x (speed)^2
Ek = 0.5 x m x v^2
-elastic potential energy = 0.5 x spring constant x (extension)^2
Ee = 0.5 x k x e^2
