direction of motion is what
volocity
100
acceleration = change in ______ / _______
speed/ time
200
speed = what / what
distance / time
200
how can velocity change
if the direction, speed, or both are changed
200
what symbol = change in
triangle
300
In order to tell how fast we were going during
the entire trip, we must find the average speed.
average speed= what / what
average speed is total distance traveled / total time traveled
300
speed describes _______ traveled changing with ________.
distance; time

what is the change in velocity divided by the time needed for the change to occur
acceleration
400
change in acceleration = _____ _____ - _______ _____
final speed - initial speed
500
If you want to know how fast you are traveling
