Activity 2: THE UPS AND DOWNS OF KE AND PE
Direction: The image below displays a roller coaster that is moving up and down from
point A to E. After studying the image, answer the questions by circling the letter of the
correct answer
1. Which letter shows the rollercoaster with the maximum potential energy?
A B
с
D
E
2. Which letter shows the rollercoaster with the least potential energy?
A A
D
3. Which letter shows the rollercoaster with the maximum kinetic energy? A B
E
4. Which letter shows the rollercoaster with the least kinetic energy? A В B.
E
5. Which letter shows the rollercoaster with more kinetic energy than coaster B? A
6. Which letter shows the rollercoaster with more potential energy than coaster B? A
B с D
7. As the cart moves from point A to point C, it continues to slow down becausethe kinetic energy is converted to potential energy. The PE
is highest as it reached the highest point
A B. с DE
8. At point, the rollercoaster has zero kinetic because it momentarily stops at this point. A B. с D E
9. As the cart moves from point D to point E, the potential energy is converted to Kinetic energy and the car speeds up. The KE is highest
at point__making the car to have enough KE to continue to go up. А B c D E
10. The KE is highest while the potential energy is lowest at point
.A
B C D E
