What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the energy that causes the particles in an object to move, which can lead to changes in temperature.

What causes the seasons on Earth?

Back

The seasons are caused by the tilt of the Earth's axis and its revolution around the Sun, leading to varying amounts of sunlight at different times of the year.

Front

What is mechanical energy?

Back

Mechanical energy is the energy that is possessed by an object due to its motion (kinetic energy) or its position (potential energy).

Front

What are conductors?

Back

Conductors are materials that allow electricity to flow through them easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, glass, and plastic.

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is a form of mechanical energy.

Front

What is light energy?

Back

Light energy is the energy that is visible to the human eye and is produced by the movement of photons.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.
