Term
| Newton's Second Law of Motion |
|
Definition
the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object
Acceleration ~ net force/mass |
|
|
Term
| Acceleration for friction (formula) |
|
Definition
| acceleration = net force/mass |
|
|
Term
|
Definition
|
|
Term
|
Definition
| the speed at which the acceleration of a falling object terminates because air resistance balances its weight. When talking about speed and direction, that is called terminal velocity. |
|
|
Term
|
Definition
| the resistive force that opposes the motion or attempted motion of an object either past another object it is on contact with or through a fluid |
|
|
Term
| Newton's Third Law of Motion |
|
Definition
| whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. |

| Law of Conservation of Momentum |
|
Definition
| In the absence of an external force, the momentum of a system remains unchanged. |
