Force and Motion
Force
| Term | Definition |
|---|---|
| Force | Push or pull applied to an object |
| Motion | The action or process of moving or of changing place or position; movement |
| Gravity | The force that attracts an object towards the center of the Earth, or towards any other physical body having mass |
| Push | To use force to move someone or something away from you |
| Pull | To hold onto and move someone or something toward yourself |
| Friction | the force that causes a moving object to slow down when it is touching another object. |
| Mass | is a measurement of the amount of matter something contains. |
| Weight | is the measurement of the pull of gravity on an object. |
| Motion | the action or process of moving or of changing place or position; movement. |
| 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 rate at which someone or something moves or travels. |
| 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. |
| 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 |
| Direction | a course along which someone or something moves |
| Velocity | the speed of something in a given direction. |
| Air resistance | the force acting on an object that is moving through air flowing in the opposite direction. |
| Momentum | the quantity of motion of a moving body, measured as a product of its mass and velocity. |
| Resist | withstand the action or effect of. |
| Deceleration | reduction in speed or rate. |
| Newton’s First Law | every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. |
| Newton’s Second Law | the acceleration of an object is directly related to the net force and inversely related to its mass |
| Newton’s Third Law | for every action there is an equal and opposite reaction |
