Chapter 4: Energy and Force
What Is Energy?
Energy is the ability to do work or cause change. It can take many forms, such as light, heat, and
movement. Energy is essential for everything we do.
Some types of energy include:
1. Kinetic Energy (Energy of motion)
2. Potential Energy (Stored energy)
3. Thermal Energy (Heat energy)
What Is Force?
Force is a push or pull that can change the motion of an object. Forces are responsible for
movement and can be used to stop or start objects.
Examples of forces include:
1. Gravity – The force that pulls objects toward the Earth.
2. Friction – The force that opposes motion between two surfaces.
