Principle of the conservation of energy
Work Done, W (joules) =
Change in object's gravitational potential energy store =
ΔEp
Change of gravitational potential energy store =
Ek=
Kinetic energy =
efficiency =
Problem: Friction between the moving parts causes heating....
how would you improve the efficiency?
