Distance, Speed, and Velocity Laura LeMay

numerical description of how far apart objects are from each other Distance numerical description of how far apart objects are from each other

SPEED *most commonly measured by meters per second. *Rate at which object moves *most commonly measured by meters per second.

Constant speed moving object continues to move in the same direction, with the same speed

motion not running at particular speed Variable Speed motion not running at particular speed (vari=change)

Velocity The speed and direction of moving object *2 ways: change in magnitude and/or a change in direction

path that something takes Direction path that something takes

location relative to a reference point Position location relative to a reference point

rate the direction or speed changes acceleration rate the direction or speed changes http://www.youtube.com/watch?v=e5Gl2LLLAGo
