acceleration

(vf-vi)/t

average speed

total distance divided by total time

linear graph

straight line on a speed-time graph

speed

meters per second

frame refrence

what do you need in order to completely determine the motion of an object

distance

determined by measuring the length between two points

resultant vector

when two or more vectors combine

free fall

accelerate at 9.8 m/s

non linear

a curve connects data points on what graph

velocity

the speed and direction in which an object is moving

relative motion

movement in relation to a frame of refrence
