Section 4c: Work and Power
Work Done = Energy transfer
When a
force
moves an object,
energy is transferred
and
work is done
Word Done equation
Gravitational potential Energy
Kinetic Energy
Power
Power is measured in Watts
Power is the
rate of energy transfer
or the rate of doing work.
when something falls its gravitational potential energy is converted into kinetic energy
energy is only useful if it can be transfered
