occurs when and object changes position

how far an object has moved

the distance and direction of and objects change in position from the starting point

the speed at a given point in time

instantanteous speed is measured on a _____

includes the speed of an object anf the direction of its motion

formula for velocity/speed=

the rate of change of velocity

formula for acceleration=

the tendency of an object to resist anu change

an obejct moving at a constant velocity keeps moving at that velocity unless a net force acts on it
