A
the limit of proportionality
5
Q
Acceleration equation
A
a = final velocity minus starting velocity/ time

Q
3 types of acceleration
A
Positive acceleration: Increases velocity
centripetal acceleration: Changes the direction of velocity, but not the size of the velocity
negative acceleration: Decreases velocity
