8th-T1 L2: Speed, Velocity, Acceleration

Draw

Draw an arrow to show the strength and direction of the force applied to the ground as the skier attempts to turn on his skis.

What force is the skier applying when he attempts to turn on his skies?

Do you think this is a light, medium or heavy force?

Open Ended

Do you think it is a light, medium or heavy force?

Open Ended

How do you think the snow will help or not help the skier move down the hill?

​How would you describe the skiers motion from when he started at the stop of the mountain to when he is halfway down?

Open Ended

List things that can move from one place to another.
