The law of conservation of energy states that energy cannot be __________ or destroyed. Only transferred to other forms.

Why is the first hill on a rollercoaster ALWAYS the tallest?

• To increase the potential energy.

• To increase the kinetic energy.

• To increase the potential and kinetic energy.

• To increase the gravitational energy.

While a roller coaster is on a track, some of the total energy has decreased. Where could that energy have been transferred to?

• To the people riding the rollercoaster.

• To the track as thermal energy caused by friction.

• To the air as light energy caused by solar.

Which rollercoaster would have the most potential energy?

• A rollercoaster that is empty.

• A rollercoaster that is full of people.

• A rollercoaster that is half full.

To get up the first big hill, a roller coaster will need help to make it to the top with two other forms of energy. What are those 2 other forms?

• Solar Energy

• Gravitational Energy

• Thermal Energy

• Mechanical Energy

• Electrical Energy

Some examples of this type of energy are a fan, bicycle, wind up toy, clock, car.

• Mechanical

• Electrical

• Light

• Thermal

• Sound
