the rate of change of velocity - acceleration, speed plus direction - velocity, how far an object has traveled - distance, speed of an object at one instant of time - instantaneous speed, the distance and direction that an object has traveled from its starting point - displacement, the speed that stays the same for a long period of time - constant speed, the rate of change in position - speed, total distance traveled divided by total time elapsed - average speed, when an objects velocity increases in same direction - positive acceleration, when an objects velocity is decreasing or opposite - negative acceleration, a change in position compared to a place or an object that is not moving - motion,
