Energizing Everything Unit 1 review

Front

What happens if the second hill of a roller coaster is higher than the first?

Back

The roller coaster would roll back down the second hill.

Front

Why does Rubber Band C make the ride spin faster?

Back

Rubber Band C is thicker so it stores more energy and moves faster.

Front

Where does gravitational energy come from?

Back

Gravitational energy comes from height.

Front

What is one source of energy for machines?

Back

Gasoline is one source of energy for machines.

Front

Why will Coaster A go faster than Coaster B?

Back

Coaster A will go faster because it's taller and has more gravitational energy stored in the first hill.

Front

What is gravitational energy?

Back

Gravitational energy is the energy an object has due to its height.

Front

What is the role of rubber bands in a model ride?

Back

Rubber bands store energy when twisted and release it to make the ride spin.

Front

What is the effect of height on energy in roller coasters?

Back

Higher hills store more gravitational energy, leading to faster speeds.

Front

What happens to energy when a roller coaster goes down a hill?

Back

The gravitational energy is converted to kinetic energy, making the coaster go faster.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.
