- Speed is the distance traveled over time. The standard unit for distance is the meter. The standard unit for time is seconds. Speed = Distance / Time
- Graphing Speed
- Distance --->
- Slope --->
- Average speed is used when speed changed twice or more. Most things that are moving change speed more than one time. Average Speed (v) = Total Distance / Total Time
- Velocity
- N
- Instantaneous speed is the rate of an object moving at any given time. When you look at a speedometer and see different speeds at different times, you are looking at the instantaneous speed.
- Speed vs. Velocity
- When graphing speed, the time goes on the horizontal axis (x-axis) and the distance goes on the vertical axis (y-axis). The line is called the slope. The slope represents the speed. Slope = Rise / Run = Y2-Y1 / X2-X1

- Velocity is speed in a given direction. Velocity can change over time. Change in velocity can be caused when speed or direction changes. Arrows called vectors are used to indicate velocity.
- S
- E
- Speed is the magnitude of velocity because speed doesn't have direction and velocity does. Velocity is a vector because it has direction and speed. When something is moving, the velocity is always changing,
