| Question | Answer |
|---|---|
| speed | rate of motion, swiftness, or velocity |
| velocity | speed of motion in a specific direction |
| vector | a quantity having magnitude and direction |
| reference point | A reference point is a fixed, stationary object or location used as a baseline to measure or compare the position, movement, or direction of other objects |
| position | an object distance and reference point |
| motion | motion is the process of changing position |
| acceleration | is a measure of the change in velocity during a period of time |
| newtons second law | states that the acceleration of an object equals the net force on the object divided by the objects mass. |
| friction | is a force that resists the sliding motion of two surfaces that are touching . |
| free body diagram | is a simple model to understand systems of subjects with an amount of applied forces |
| contact force | is a push or a pull on one object by another object that's touching it. |
| net force | is the sum of all the forces acting on an object |
| newtons first law of motion | states that an object in motion will stay in motion, and an object at rest will stay at rest unless acted on a force |
| non contact force | is a force that one object can apply force to another object with out touching it |
| gravity | is an attractive force that exists between all objects that have mass |
| field | is a region of space that has physical quantitu (such as a force) at every point. |
| weight | is the gravitational force exerted on an object. |
| new tons third law of motion | Newton's third law of motion states that for every action (force) in nature, there is an equal and opposite reaction. |
| force pair | two equal-in-magnitude, opposite-in-direction forces that occur simultaneously when two objects interact |
| normal force | the upward supporting force exerted by a surface perpendicular to an object resting on it, preventing it from passing through |
| elastic collision | a type of collision where both total momentum and total kinetic energy are conserved |
| inertia | the inherent resistance of any physical object to a change in its state of motion or rest, fundamentally measured by its mass |
| displacement | the moving of something from its place or position. |
| force | a push or a pull on an object |
| Inelastic Collision | a collision where total kinetic energy is not conserved, converting some into heat, sound, or deformation, although momentum is always conserved |
