Energy: Conservation and Transfer

Front

What is conduction?

Back

Conduction is the transfer of energy through direct contact between materials. For example, when you touch a hot stove, heat is transferred to your hand.

Front

What is convection?

Back

Convection is the transfer of energy through the movement of fluids (liquids or gases). For example, warm air rising and cool air sinking creates a convection current.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. For example, the heat from the sun reaches the Earth through radiation.

What type of energy is produced when a guitar string vibrates?

Back

Sound energy is produced when a guitar string vibrates.

Front

What is magnetism?

Back

Magnetism is a force that attracts certain metals, such as iron, and is caused by the motion of electric charges.

Front

What type of energy produces light in a lamp?

Back

Electrical energy is converted into light energy when you turn on a lamp.

Front

What is the most magnetic material?

Back

Iron is the most magnetic material.

Front

What is energy conservation?

Back

Energy conservation is the practice of using less energy by being more efficient or reducing waste.

Front

What is an example of energy transfer?

Back

An example of energy transfer is when you heat a pot of water on the stove; heat energy moves from the burner to the pot.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.
