1. Gravitational Force: This is the force of attraction between any two objects with mass. The more massive the objects, the stronger the gravitational pull. This is what keeps us on the ground and causes the Earth to orbit the sun.
2. Electromagnetic Force: This force involves interactions between electrically charged particles. It's responsible for holding atoms together, creating light and magnetism, and powering everything from electricity to the internet.
3. Strong Nuclear Force: This is the strongest force in the universe, acting within the nucleus of an atom. It binds protons and neutrons together, overcoming the electromagnetic repulsion between the positively charged protons. Without this force, the universe would be very different, and atoms wouldn't exist as we know them.
