N1st law and motion
| Question | Answer |
|---|---|
| Distance | How far you have traveled between two positions . it is a scalar quanity |
| Displacement | change in position it is the straight line distance between your starting position and ending position . it is equal to final minus initial position it can be positive or negative it is a vector quantity |
| scalar | quantity that only requires magnitude (how big) |
| vector | quantity that requires both magnitude (how big) and directions |
| speed | how fast something is moving |
| velocity | rate at which position changes. it is equal to displacement divided by time |
| newtons's first law | AKa the law of inertia |
| mass | a measure of the amount of matter an object contains |
| inertia | the resistance an object has to change in its motion |
| force | any push or pull (interraction) that can cause a change in motion |
| net force | the combination of all of the forces on an object |
| balanced | when the net force in both the horizontal and verticle directions is 0 n. these cause motion to remain unchanged |
| unbalanced force | when the net force in both the horizontal and vertical directions is not 0 N. |
| gravitaional force | a non-contact force between two objects that is most apparent close to a large object such as a planet , the direction of the force is general towards the center of the other object |
