What is energy? The ability to do work
What is work? The ability to move something
Any change in motion requires energy
The energy of motion is called kinetic energy
The amount of kinetic energy depends on an object's speed and mass
An object will have more kinetic energy if it moves faster
An object will have more kinetic energy if it has more mass
Stored energy is called potential energy
An object has the most potential energy when it is as high as it can be
As an object starts to go downward, it ___________ potential energy. loses
Can potential energy be changed to kinetic energy? yes
Can kinetic energy be changed to potential energy? yes
Objects that are __________ or _______________ also have potential energy. stretched, squeezed (rubber band, wind-up toy)
