Energy Change and Conservation

Front

What is energy change?

Back

Energy change refers to the transformation of energy from one form to another, such as from chemical energy in wood to thermal energy when it burns.

Front

What is energy conservation?

Back

Energy conservation is the practice of using less energy by being more efficient or reducing waste, ensuring that energy is not lost.

Front

What are the two main types of energy?

Back

The two main types of energy are kinetic energy (energy of motion) and potential energy (stored energy).

Front

What happens to energy when wood is burned?

Back

When wood is burned, chemical energy is transformed into thermal energy (heat) and electromagnetic energy (light).

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 energy stored in an object due to its position or state.

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object or system to another without changing its form.

Front

How does energy transformation occur?

Back

Energy transformation occurs when energy changes from one form to another, such as from potential energy to kinetic energy.

Front

What is an example of energy transformation in a swing?

Back

As a swing moves from its highest point to its lowest point, potential energy is transformed into kinetic energy.

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.
