kinematics

kinematics

the study of motion of objects

scalar quantities

have magnitude, no direction

positivie

vector quantities

have direction and magnitude

positive or negative

distance

how much ground an object has covered during its motion (scalar)

displacement

how far out of place an object is

overall change in position

vector

displacement equation

xf-xi

avg speed

distance traveled/time elapsed

avg velocity

displacement/time

motion maps

represent x v and a of an object at intervals of time

difference between position and displacement

position graphs can start from a value other than zero
