Work |
anytime you exert force on an object that causes the object to move |
|
|
Energy |
is the ability to do work or cause change |
|
|
Power |
is the rate at which work is done |
|
|
Kinetic & Potential Energy |
Two basic types of energy |
|
|
Since the transfer of energy is work, then the power is the rate at which energy is transferred, that is the amount of energy transferred in a unit of time |
= energy transferred/ time |
|
|
Kinetic Energy |
depends on the objects speed and mass 1/2*mass*speed2 |
|
|
Potential Energy |
is the energy that results from the position or shape of an object |
|
|
Gravitational potential energy |
object is equal to the work done to lift it Weight*height |
|
|
Elastic Energy |
is the energy accosiated with objects that can be comprpmised
