When two objects collide, what happens to the energy of each object?
The diagram below shows a roller coaster cart at four positions as it moves along a track. As it moves, the cart has varying levels of kinetic and potential energy. However, throughout the entire ride, the total amount of energy (potential plus kinetic) is conserved or remains the same. Explain why this is true.
HINT: Think about the Law of Conservation of Energy AND how energy can be transformed.
Sentence Starter:
The total amount of energy remains the same because ....
EXTRA CREDIT
You own a roller coaster and you are trying to increase its speed! You have decided to make the “dropping point” for the ride 50 feet taller. How will this impact the amount of energy that can be transformed? How will this improvement change the amount of Potential and Kinetic energy in the ride?
Sentence Starter:
This impacts the amount of energy by ....
This will change the total amount of energy by....
