1. It is the total length of path traveled by a moving object regardless of the direction of motion.

1. The shortest distance between the object’s initial and final position.

1. What causes an object to move?

1. Car travels along a straight road 100 m east then 50 m west. Find the DISTANCE of the car.

1. It tells you how fast or slow an object is moving.

1. It is a measure of how fast something moves in a particular DIRECTION.

1. It is the rate of change in velocity of a moving object per unit of time.
