energy

what does dissipation mean?
describes ways in which energy is wasted.
1 of 7
what is an example of dissipation?
heat energy coming off a radio
2 of 7
what does the conservation of energy say?
energy can be transfered usefully, stored or disipated and it cannot be destroyed or created
3 of 7
give an example of conservation of energy
when a parachuter jumps out of a plane he begins to lost gravitational potential energy as his height decreases and he gains kinetic energy as speed increases.
4 of 7
how to calculate kinetic energy
1/2 x mass x speed squared
5 of 7
how to calculate elastic potential energy
1/2 x spring constant x extention squared
6 of 7
how to calculate gravitational potential energy
mass x gravitational field strength x height
