1. GPE and KE Roller Coaster Question

2. The roller coaster starts from A and travels to F, where it stops by hitting a bumper. At E the roller coaster is filled with water. A ) At which two points does the roller coaster have no kinetic energy? ______ and ___________ A F No Kinetic energy – NOT moving

3. The roller coaster starts from A and travels to F, where it stops by hitting a bumper. At E the roller coaster is filled with water. b) At which point does the roller coaster have the most gravitational potential energy? ___________ A Greatest GPE----- Highest position from the ground

4. The roller coaster starts from A and travels to F, where it stops by hitting a bumper. At E the roller coaster is filled with water. E Least GPE----- nearest from the ground Kinetic energy – still moving c) At which point does the roller coaster have some kinetic energy and the least gravitational potential energy? ______________

5. d) Why the moving car comes to a stop when it hits the bumper at F? The kinetic energy of the moving car is converted to sound and heat energy. No more kinetic energy.

6. Forces Roller Coaster Question

7. The roller coaster starts from A and travels to F, where it stops by hitting a bumper. At E the roller coaster is filled with water. Gravity / gravitational force a) The cars are not powered by a motor. What force causes the roller coaster to move along the track from B to C?

8. The roller coaster starts from A and travels to F, where it stops by hitting a bumper. At E the roller coaster is filled with water. 1) friction b) When a car splashes through the water at E, it slows down. What force acts on the car to slow it down? 1) Water resistance
