force and motion
| Termg | Definition |
|---|---|
| gravity | an invisible force that pulls objects toward each other |
| mass | the amount of matter or substance that makes up an objec |
| weight | a measure of the gravitational force with which an object is drawn to the center of a massive second object |
| pull | the force of bringing an object closer. |
| push | when you use force to move a thing (object) away from you. |
| newtons 1 law | intersiona |
| newton's second law | motion |
| newton's 3 law | for every action there is an equal and opposite reaction |
| friction | the resistance of motion when one object rubs against another |
| motion | a change in position compared to a place or an object that is not moving |
| velocity | speeding in a specific direction |
| force | an action that changes or maintains the motion of a body or object |
| inertia | the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. |
| speed | the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. |
| air restsitance | the force acting on an object that is moving through air flowing in the opposite direction |
| momentum | a measurement of mass in motion. |
| resist | to fight again |
| position | the place where someone or something is in relation to other people or things. |
| axis | the imaginary straight line that something (such as the Earth) turns around. |
| direction | a course along which someone or something moves Velocity |
| unbalanced force | are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving. |
| acceleration | the rate at which the speed of a moving object changes over time |
| deceleration | to reduce the speed of |
