|
Force |
A push or a pull. Measured in newtons by the acceleration it produces on a standard isolated object. |
|
|
Inertia |
An objects resistance to a change in its velocity. |
|
|
Inversely Proportional |
A relationship in which two quantities have a constant product. If one quantity increases by a certain factor, another decreases by the same factor.
|
|
|
Kilogram |
The standard international system unit of mass. About 2.2 lbs. |
|
|
Kinetic Friction |
The frictional force between two surfaces in relative motion. Does not really depend on relative speed.
|
|
|
Law of Inertia |
Newton's first law of motion. |
|
|
Mass |
A measure of the quantity of matter in an object. Measured in kilograms. |
|
|
Newton's first law of motion |
The velocity of an object remains constant unless an unbalanced force acts on the object. |
|
|
Newton's second law of motion |
The net force of an object is equal to its mass times its acceleration. The net force and acceleration are vectors that always point in the same direction. |
|
|
Newton's third law of motion |
If an object exerts a force on a second object, the second object exerts the same amount of force on the first object. |
|
|
Newton |
The standard unit of force. A net force of 1 Newton accelerates a mass of 1 kilogram at a rate of 1 meter per second per second. |
|
|
Proportional |
A relationship in which two quantities have a constant ratio. If one quantity increases by a certain factor, the other increase by the same factor. |
|
|
Static Friction |
The frictional force between two surfaces at rest relative to each other. This force is equal and opposite to the net applied force if the force is not large enough to make the object accelerate. |
