Force and Motion
science
| Question | Answer |
|---|---|
| Gravity | is a force that pulls everything and everybody towards earth. |
| Mass | is the amount of matter in an object |
| Weight | a measure of the force Earth's gravity on the mass of the object |
| Newton's first law | inertia |
| Newton's second law | acceleration |
| Newton's third law | action and reaction |
| force | strength or power exerted upon an object. |
| Push: | to use force to move (someone or something) forward or away from you |
| Pull: | to hold onto and move (someone or something) in a particular direction and especially 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 |
