2. A B C D E 2. The bar graph shows the energy of the Skater, where could she be on the track?

3. A B C D E 3. The pie graph shows the energy of the Skater, where could she be on the track? KE PE

4. PE KE A. B. C. D. 1 3 4 2 4. If the ball is at point 4, which chart could represent the ball’s energy?

5. 1 3 4 2 5. If a heavier ball is at point 4, how would the pie chart change? KE • No changes • The pie would be larger • The PE part would be larger • The KE part would be larger PE

6. At 4 Next step 1 3 4 2 6. As the ball rolls from point 4, the KE bar gets taller. Which way is the ball rolling? • Up • Down • not enough info
