Motion
| Question | Answer |
|---|---|
| motion | motion is change in position over time relative to a reference point |
| What are four ways to describe motion? | distance, speed, velocity and acceleration |
| Speed | the distance an object travels per unit of time |
| velocity | speed in a given direction |
| distance | the measurement between two points |
| accelearation | the rate of change in velocity |
| What is the equation of speed? | S=D/T |
| How do you determine speed on a graph? | the slope. a steeper slope equals a faster speed. |
| What does a graph look like if the object is at rest? | no change in y. It is a horizontal line |
