Speed=
distance/time
The two factors that determine velocity include
Speed direction/ distance time
Acceleration =
2 velocity- 1 velocity /time
What do we do with two velocities when they are in the same direction?
+
What do we do with two velocities when they are in opposite directions
-
-Total distance/total time.
average speed
-Speed at any one given moment.
instantaneous speed
-The rate at which velocity changes (a change in speed or direction over time).
acceleration
-The place or object that you compare another object to in order to determine if it is in
motion.
reference point
-The technical term for deceleration.

What was the acceleration of a car that went from 60 m/s to 72 m/s in 4 s?
3 m/s 2
Mrs. Mousadis was riding her skateboard. She was trucking along at about 5 m/s when all of a
sudden she hit some bad pavement and 1.5 seconds later she found herself going only 2 m/s.
Calculate her acceleration.
