IQWST Unit 2 - Why Do Some Things Stop While Others Keep Going?

Front

What types of energy are involved when a rubber ball bounces?

Back

Kinetic energy, elastic energy, and gravitational energy are all involved.

Front

What change does NOT affect the energy of a roller coaster car?

Back

Increasing the volume of the roller coaster car does not change its energy.

Front

Does a decreasing bounce height of a ball contradict the idea of energy conservation?

Back

No, the total amount of energy of the ball and the surroundings remains constant, even if kinetic energy decreases.

Front

What happens to the gravitational energy of a roller coaster car as it travels downhill?

Back

The gravitational energy decreases.

Front

What is an example of potential energy?

Back

Gravitational energy is an example of potential energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion.

Front

Define potential energy.

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is energy conservation?

Back

Energy conservation is the principle that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does height affect gravitational energy?

Back

Gravitational energy increases with height and decreases as the height decreases.

Front

What is elastic energy?

Back

Elastic energy is the potential energy stored in an object when it is compressed or stretched.
