Revisiting the bouncing ball

Open Ended

What are the similarities between the energy conversion diagrams for the bouncing ball, the pendulum, and the rolling can?

Similarities of the conversion diagrams

• They are represented as pie charts

• They describe conversions between different types of energy

• The segments in the pie charts represent different types of energy

• The sizes of the segments represent approximate, not exact, amounts of energy

• The size of the pie diagram never changes

Open Ended

Why does the size of the pie chart never change?

Open Ended

Why do you think a ball stops bouncing?

Open Ended

Your teacher showed you an animation of a ball bouncing until it stopped. What types of energy do you think the ball had at points 1-7? What types of energy conversions occurred between these points?
