Energy Transformations Flashcard

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into light energy.

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, typically consisting of a power source, wires, and electrical devices.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electric current is interrupted, and devices in the circuit, like bulbs, will not light up.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (stopping the flow) or closing (allowing the flow) the circuit.

Front

Which materials are good conductors of electricity?

Back

Good conductors of electricity include metals like copper and aluminum, which allow electric current to flow easily.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the energy of moving particles.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibration of electrically charged particles.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object; it is the energy associated with the motion and position of an object.

Front

What is the difference between absorb and reflect in terms of light?

Back

Absorb means to take in light energy, while reflect means to bounce back light energy without absorbing it.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow and power devices.
