Work, energy and power
WORK DONE ≡ENERGY TRANSFERRED
Work done in raising object:
F = mg
W = FH
= mgh ⟹ EP = mgh
Work done can be used outside of mechanics, such as W = QV in
electricity and also P = Et , P = Wt where E = W = energy/work .
It can also be used to get the engine equation: P= F v, where P =
power , F =force provided by engine (thrust) and v = velocity.
Energy is always conserved.
Work done by a force
work done (by a force) = force x displacement in the direction of the
force.
