Slope, Distance, Velocity, Time
| Question | Answer |
|---|---|
| The slope of a distance vs time graph is equal to | speed |
| The slope of a speed vs time graph is equal to | acceleration |
| What is the difference between average speed and instantaneous speed? | Average speed is total distance divided by total time. Instantaneous speed is speed you have at a specific point on the journey. |
| What is the difference between speed and velocity? | Speed is how fast you are going over a certain distance. Velocity is speed and direction. |
| What is the difference between acceleration and speed? | Speed is distance over time. Acceleration is how much your speed changes over time |
| What type of acceleration is cruise control on a straight road? | zero acceleration |
| What type of acceleration is applying brakes on a truck? | deceleration |
| What type of acceleration is dropping a ball from the roof? | acceleration (due to gravity) |
| What type of acceleration is a motorcycle parked in a parking log? | zero acceleration |
| What type of acceleration is a car turning a sharp corner? | acceleration |
| time = ? | distance divided by velocity |
| distance = ? | velocity multiplied by time |
| velocity (speed) = ? | distance divided by time |
