How can i summerise the principles of conversion in relation to Gravitational potential energy, Kinetic energy, work done and velocity

Gpe converted into kinetic, chemical converted into kinetic from food. Work done increases as the higher the kinetic energy. the further after the ski jump the higher the velocity until reaches terminal velocity where there is no resultant force. If you want more detail ask. :biggrin:

total energy is equal to GPE + KE
work done can be calculated using the work energy principle W=(1/2MV^2)-(1/2MU^2) where U is starting velocity and V is final Velocity there for linking work to velocity
