Speed vs. Velocity
Directionally challenged Steve has a hard time with velocity!!

2. Velocity Velocity is equal to distance divided by time
Velocity = Distance / Time
The unit for speed and velocity is m/s (meters per second)
Velocity always has a direction, this is usually indicated with a negative or positive sign
Positive = moving forward
Negative = moving backward
Velocity = Speed + direction

3. Direction
Any value that is expressed as a number and a direction is called a VECTOR!
Velocity is a vector
Speed is NOT a vector
Why?
Speed has NO DIRECTION

4. The Parallel Parker
A car parking in parallel is initially traveling forward so the speed and velocity is positive
The car then stops, now the velocity and the speed is 0.
The car then shifts into reverse and travel at a speed of 1m/s, what is its velocity?
-1m/s (note the negative sign to indicate the car is traveling in reverse)
The car then stops again so its velocity and speed are 0.
Finally the car pulls forward and the speed and velocity are both positive
