Front

What happens to an object's potential energy when it falls?

Back

It is converted into kinetic energy.

Front

What is the relationship between the distance a catapult is pulled back and the potential energy stored?

Back

The farther a catapult is pulled back, the greater the potential energy stored.

Front

What does sustainable design involve?

Back

Building for efficiency and long-term resource conservation.

Front

What is a major benefit of hydropower?

Back

It relies on renewable resources.

Front

What do catapults use stored potential energy for?

Back

To propel objects through the air.

Front

Define potential energy.

Back

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

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion.

Front

What is the principle of energy transformation?

Back

Energy can change from one form to another, such as potential energy converting to kinetic energy.

Front

What is renewable energy?

Back

Renewable energy comes from sources that are naturally replenished, like sunlight, wind, and water.

Front

What is the role of efficiency in sustainable design?

Back

Efficiency in sustainable design minimizes waste and maximizes resource use.
