| In a Speed vs Distance graph, which one is the dependent variable? | Speed |
| In a Speed vs Distance graph, which one is the independent variable? | Distance |
| Does the dependent variable go on the X or Y axis? | Y |
| Does the independent variable go on the X or Y axis? | X |
| How do you find the speed or velocity of an object | Divide the Distance by the Time |
| Why are graphs useful? | They allow us to make predictions |
| What is the slope on a distance vs time graph? | It can show you the speed |
| What does a steep slope tell you on a distence vs time graph? | The speed is greater |
| What is the AVERAGE speed? | The TOTAL distance divided by the TOTAL time |
| What is INSTANTANEOUS speed? | The speed at a given point in your journey |
| What is acceleration? | The rate at which speed changes? |
| How do you find the acceleration? | Take the final speed - the initial speed and divide it by the time |
| How do you calculate the speed from a position vs. time graph? | Rise divided by run |
| What is the slope of a position vs time graph equal to? | Velocity |
| What is the slope of a speed vs. time graph equal to? | Acceleration |
| What does a small, not steep slope indicate about the speed? | The speed is slow |
| What 2 things can change in order to have acceleration? | velocity and/or direction |
| A skier accelerates from 10m/s to 40m/s in 3 sec. What is his acceleration? | 10 m/s/s |
| On a speed vs. time graph, what is happening if the line is going up? | Positive Acceleration (speeding up) |
| On a speed vs. time graph, what is happening if the line is a flat horizontal line? | There is zero acceleration which means you are going at a constant speed. |
| On a speed vs. time graph, what is happening if the line is going down? | Negative acceleration (deceleration) |
| Slope | Rise/Run |
| Speed | Distance divided by time |
| Acceleration | A change in speed (velocity) or direction |
| Deceleration | A change in speed in a negative direction |
| Instantaneous speed | The speed at a given point in time (at that moment) |
| Average speed | The TOTAL distance divided by the TOTAL time |
| If the line is a flat, horizontal line on a Position vs. Time graph, what motion is occurring? | Not moving, stopped |
| If the line CURVES upward on a Distance vs. Time graph, what kind of motion is occurring? | Speeding up |
| If the line goes back towards the x-axis, in a negative trend, what type of motion is occurring if it is a Position vs. Time graph? | Returning to starting position |
| Can velocity be negative? | YES |
| Can speed be negative? | NO |
| Can acceleration be negative? | YES |
| Displacement can be negative. True or False? | TRUE |
| If Distance is in meters and Time is in seconds, what should a Title for a graph of that motion be? | Distance (cm) vs. Time (s) |
| If you walk to school 1 mile, then return home another mile, what is your displacement? | ZERO MILES |
