Energy Conservation in Roller Coasters

What is the principle of conservation of energy?

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy can be created and destroyed.

• Energy remains constant without any transformation.

• Energy is only in the form of kinetic energy.

At the highest point of a roller coaster, what type of energy is at its maximum?

• Gravitational potential energy

• Kinetic energy

• Thermal energy

• Chemical energy

What is the formula for calculating kinetic energy?

• KE = 0.5 * m * v^2

• KE = m * g * h

• KE = m * v

• KE = m * g

What happens to the gravitational potential energy as the roller coaster descends?

• It is converted into kinetic energy.

• It remains constant.

• It is converted into thermal energy.

• It increases.

If a roller coaster has a mass of 500 kg and is at the top of a 50-meter hill, what is its gravitational potential energy?

• 245,000 joules

• 25,000 joules

• 2,450 joules

• 24,500 joules
