Energy
|
the capacity to do work
|
|
kinetic energy
|
the energy of an object that is due to the objects motion
|
|
Potential Energy
|
The energy that an object has because of the position, shape, or condition of the object
|
|
Mechanical Energy
|
The amount of work an object can do because of the object's kinetic and potential energies.
|
|
Energy Conversion
|
a change from one form of energy to another
|
|
Friction
|
a force that opposes motion between two surfaces that are in contact
|
|
law of conservation of energy
|
the law that states that energy cannot be created or destroyed but can be changed from one form to another
|
|
Nonrenewable resource
|
a resource that forms at a rate that is much slower than the rate at which it is consumed

|
Newtons first law
|
Objects at rest stay at rest until a force is applied
objects in motion tend to stay in motion until a force is applied |
|
Newtons Second Law
|
Friction = Mass x Acceleration
|
|
Newtons Third Law
|
Action --> equal (amount of force) opposite in direction reaction
|
|
Momentum
|
P = Mass x Speed
