|
power
|
power=energy transferred
________________ time |

|
power and energy
|
If the transfer of energy is work, then power is the rate at wich energy is transferred, or the amount of energy transferred in a unit of time.
|
|
|
Basic kinds of energy
|
The two basic kinds of energy are kinetic energy and potential energy.
|
|
|
kinetic energy
|
the energy an object has due to it's motion is called kinetic energy.
|
|
|
kinetic energy formula
|
kinetic energy=50%times mass times velocity
|
|
|
potential energy
|
Stored energy that results from the position or shape of an object is called potential energy.
|
|
|
gravitational potential energy
|
potential energy related to an objects hight is called gravitational potential energy.
Weight times Height |
|
|
elastic potential energy
|
the potential energy assosiated with objects that can be streched or compressed is called elastic potential energy.
