As a child swings on a swing set explain how the potential and kinetic energy of the child changes. When would each be the highest?
What is As the child moves up to the highest point the potential energy is the highest because the child is farther off the ground. The kinetic energy is the highest as the child passes through the lowest point because they are traveling the fastest?

Explain how the rotational speed vs the tangential speed of a lady bug changes as she moves from the outer edge of a spinning disk closer to the center.
What is the rotational speed is the same throughout and the tangential speed decreases because she's covering less distance with each spin?
