Motion and Reference Points

There is always a change in position when an object moves.

We can describe a moving object by using anything that stays in place.

A moving car can be used as reference point to describe the position of a moving vehicle.

A moving object never changes its position.

Living things around you can be used as reference points.

Your body is in motion when you are sitting down.

Street signs, bridges, traffic lights, and buildings are examples of reference points.

A tree along a highway can be used as reference point for moving vehicles.
