equation for work done
work done = force x distance moved
work done =
energy transferred
equation for gravitational potential energy
gravitational potential energy =
mass x gravitational field strength x height
equation for kinetic energy
kinetic energy = ½ x mass x speed2
equation for power
power = work done/time taken
definition of power
the rate of energy transfer/the rate of doing work
definition of work done
work done on an object is the energy you put in (lift, stretch or speed up an object)
the energy gained can be in the form of:
GPE
kinetic energy
work
elastic potential energy
etc.
