|
Newton |
A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second. |
|
|
Speed |
Distance traveled per unit of time. |
|
|
Acceleration |
Change in velocity. |
|
|
Velocity |
A variable that tells you speed and direction. |
|
|
Force |
A push or pull |
|
|
Newton's First Law |
An object at rest remains at rest, and an object in motion stays in motion at a constant speed and straight line unless acted upon by and unbalanced force. |
|
|
Newton's second law |
Acceleration depends on the objects mass and on the net force acting on the object. |
|
|
Newton's Third Law |
For every action, there is an equal and opposite reaction. |
|
|
Inertia |
An objects resistance to change it's motion. |
|
|
Mass |
A measure of the amount of matter in an object. |
|
|
Kilogram |
SI unit for mass. |
|
|
Meters Per Second |
SI unit for speed. |
|
|
Meters Per Second Squared |
Unit for acceleration. |
|
|
Balanced Force |
Equal forces acting on an object in opposite directions. |
|
|
Unbalanced Force |
Forces that combine to produce a net force that is not equal to zero and cause the velocity of the object to change. |
|
|
Normal Force |
Contact force exerted by a surface on an object. Acts perpendicular to and away from the surface. |
|
|
Applied Force |
Force applied to an object by another object. |
|
|
Reaction Force |
The force that is equal in strength and opposite in direction the the action force, which acts simultaneously on whatever is exerting the action force. |
|
|
Action Force |
The name often given to the force exerted by the first object on a second object. |
|
|
Force Gravity |
In force diagrams, always down. |
|
|
Motion |
An object's change in position relative to a reference point. |
