Speed - is the distance traveled divided by the time needed to travel the distance
Acceleration - is the change in velocity divided by the amount of time required for the change to occur (speeding up or slowing down)
SPEED = DISTANCE (6M) TIME (3S) = 2m/s
ACCELERATION = FINAL SPEED-INITIAL SPEED(8m/s - 2m/s)=6ms =.5m/s2
TIME (12s)
What is the difference between speed and acceleration?
