The fundamental forces of nature are like invisible glue that hold the universe together. They are everywhere and all around us. There are four fundamental forces of nature: gravity, electromagnetism, the strong force, and the weak force.
Gravity is a force that pulls things towards each other. This force is what keeps us on the ground and the planets in the sky.
Electromagnetism is when electric energy and magnetic energy mix together. It is what makes electricity, lightning, and magnets.
The strong force holds the particles inside of atoms together. It is the strongest force.
The weak force is very weak and it helps particles change from one thing to another.
