Energy Unit: Key Concepts

Front

How does a windmill generate energy?

Back

A windmill is a structure that transforms wind energy into electrical energy using blades.

Front

What are indicators of energy?

Back

Indicators of energy include motion, heat, light, and sound, which show that energy is present or being transferred.

Front

What is energy transfer?

Back

Energy transfer is the movement of energy from one place or object to another, such as a ball bearing transferring its energy to another object in a collision.

Front

What is transformation of energy?

Back

Transformation of energy is the process of changing energy from one form to another, like electrical energy to sound energy.

Front

What are 5 types of energy?

Back

Types of energy include mechanical, thermal, electrical, light energy, and sound energy.

Front

What are currents in the context of energy?

Back

Currents refer to the flow of electric charge in a conductor.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source through a conductor and back.

Front

How does this example of energy transformation happen in daily life?

Back

When you turn on a lamp, electrical energy is transformed into light and heat energy.

Front

How does a battery work in a circuit?

Back

A battery transfers electrical energy through a circuit, creating an electric current.

Front

What is the role of conductors in a circuit?

Back

Conductors allow electric current to flow easily through them, connecting different parts of a circuit.
