Describing and Predicting Motion
Look at the skier in the picture. How does the position of the skier change?
We know that something has moved when it has changed position. When something is in the process of changing position, we say it is in motion. We can describe and measure motion in different ways. We can describe motion in many ways. A bowling ball moves in a straight line towards the pins. On a swing you move back and forth. Think about the different things in a playground. How can you describe your motion when you play on different equipment?

On the seesaw, you move up and down. On a carousel, you move round and round.

What’s your favorite ball sport? What words can you use to describe the motion of the ball?
