Amplify- Harnessing Human Energy

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass, pulling them toward each other. On Earth, it pulls objects toward the center of the planet.

What happens to energy when it changes types?

Back

Energy converts from one form to another, such as kinetic energy converting to potential energy or light energy.

Front

What type of energy does a ball rolling down a hill have?

Back

Kinetic energy, which is the energy of motion.

Front

What is a system in scientific terms?

Back

A system is a set of interacting parts that form a complex whole, often studied to understand how those parts work together.

Front

What type of energy does a wind-up toy have when it is moving?

Back

A wind-up toy has both kinetic energy (due to its motion) and potential energy (stored energy when wound up).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as an object at height.

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object or system to another, such as heat moving from a hot object to a cooler one.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy conversion?

Back

An example of energy conversion is a roller coaster, where potential energy at the top converts to kinetic energy as it descends.
