|
Impulse |
The product of force and time interval during which the force acts. |
|
|
Law of conservation of momentum |
In the absence of the net external force the momentum of an object or system of objects is unchanged |
|
|
Elastic |
Term applied to a material that returns to its original shape after it has been stretched or compressed |
|
|
Inelastic |
Term applied to a material that does not return to its original shape after it has been stretched or compressed |
|
|
Momentum |
The product of the mass and velocity of an object |
|
|
Mass |
A measure of an object's inertia |
|
|
Energy |
The property of an object or system which enables it to do work |
|
|
Law of conservation of energy |
Energy cannot be created or destroyed. |
|
|
Rotation |
The spinning motion that takes place when an object rotates about an axis located within the object |
|
|
Revolution |
Motion of an object turning around an axis outside the object |
|
|
Centripetal |
A center directed force that causes an object to move in a curved path |
|
|
Centrifugal |
An apparent outward force on a rotating or revolving body |
|
|
Inertia |
The reluctance of any body to change its state of motion |
|
|
Axis |
The straight line around which an object may rotate or revolve |
|
|
Acceleration |
The rate at which velocity is changing. The change may be in magnitude direction or both |
|
|
Force |
Any influence that tends to accelerate an object; a push or pull |
|
|
Linear Speed |
The path distance moved per unit of time |
|
|
Angular momentum |
Product of rotational inertia and rotational velocity |
|
|
Friction |
The force that acts to resist the relative motion of objects or materials that are in contact |
|
|
Normal force |
For an object resisting on a horizontal surface the upward force that balances the weight of the object |
|
|
Weight |
The force on a body due to gravitational attraction of another body |
