Imagine you're on a playground swing and want to go higher. Describe the motion of the swing and explain how you’d increase your height by moving your body.

In your own words, describe the difference between distance and displacement. Could you give an example of when these would be the same and when they would be different?

Picture yourself running a lap around a track. How would you explain the difference between the distance you ran and your displacement? Would they be the same if you only ran halfway around the track?

Think about pouring water into a glass. Describe how gravity affects the water as you pour and explain what would happen if you poured the water in a place with weaker gravity, like the Moon.

Suppose you’re throwing a ball straight up into the air. Describe how its speed and direction change on the way up and the way down. At what point is its speed zero?
