|
|
Term
|
Definition
| The average speed of any object is the total distance traveled divided by the travel time. |

|
Term
|
Definition
| A push or pull that one object exerts on another. |
|
|
Term
|
Definition
| The force that opposes the sliding motion of two surfaces that are in contact. |
|
|
Term
|
Definition
| The instantaneous speed of an object is the speed at a single instant of time. |
|
|
Term
|
Definition
| When two or more forces act on an object at the same time. |
|
|
Term
|
Definition
| The force that acts in the opposite direction to the motion of a surface sliding on another surface. |
|
|
Term
|
Definition
| The distance of an object travels per unit of time. |
|
|
Term
|
Definition
| The frictional force that prvents two surfaces in contact from sliding past each other. |
|
|
Term
|
Definition
| When forces combine to produce a net force that is not zero. |
|
|
Term
|
Definition
| A quantity that is specified by both size and a direction. |
|
|
Term
|
Definition
| The velocity of an object is the speed of an object and its direction of motion. |
|
|
Term
|
Definition
| Acceleration toward the center of a curved or circular path. |
|
|
Term
|
Definition
| The net force exerted towards the center of a curved path. |
|
|
Term
|
Definition
| If the net force on an acting on an object is zero, the object remains at rest, or if the object is moving, it continues in a straight line with constant speed. |
|
|
Term
|
Definition
| An attractive force between any two objects that depends on the masses of the objects and the distance between them. |
|
|
Term
|
Definition
| The tendency of an object to resist a change in motion. |
|
|
Term
| Law of conservation of momentum |
|
Definition
| If a group of objects exerts forces on each other, their total momentum doesn't change. |
|
|
Term
|
Definition
| The momentum of an object is the product of its mass and velocity. |
|
|
Term
|
Definition
| It states that the acceleration of an object is the same direction as the net force on the object, and that the acceleration can be calculated from an equation. |
|
|
Term
|
Definition
| It describes action-reaction pairs the way: When one object exerts a force on a second object, the second one exerts a force that is equal in stength and opposite in direction. |
