Definition
| push or pull on an object and is measured in newtons. |
|
|
Term
| Newton's first law also states that objects in motion |
|
Definition
| stay in motion unless acted upon by something else. |
|
|
Term
| On earth objects in motion are acted on |
|
Definition
| by the force of gravity and air friction so it does not stay in motion. |

|
Term
| Instantaneous Speed is the speed we are going |
|
Definition
|
|
Term
| Newton's first law states |
|
Definition
| if an object is in motion it stays in motion unless acted upon by an outside force and an object at rest stays at rest unless acted upon by an outside force. |
|
|
Term
| The velocity of an object is |
|
Definition
| both its speed and direction |
|

Term
| The object is motionless has a net force of |
|
Definition
|
|
Term
| Net force is the sum of all the forces acting upon a object including |
|
Definition
| the force of gravity of pushing down and the forces of air currents, or the forces pushing up on an object |
|
|
Term
| Normal force is the force that cancels |

|
Definition
|
|
Term
| Why might a person think the earth was the center of things? |
