A measure of how far apart two objects are
Distance
The following are used to determine what?
Distance Time
Speed
Speed= Distance/Time
(Distance divided by time)
What 2 things do we need to calculate Velocity?
Speed and Direction
Defined as the total change in position compared to the STARTING POINT
Displacement
The following are used to determine what?
Distance Time Direction
Velocity

The red ranger runs South at 10 Meters in Ten seconds
The green ranger runs North at 10 meters in 10 seconds
The Pink ranger runs West at 10Meters in 10seconds
What are their speeds and velocities
All are traveling at the same speed of 1 meter per second. Velocities differ by direction.
Red- south, Green North, Pink West
