* Gravity: This is the force of attraction between any two objects with mass. It's what keeps us on the ground and what causes the planets to orbit the sun.

* Electromagnetism: This force governs the interactions between electrically charged objects. It's responsible for things like magnetism, light, and the chemical bonds that hold molecules together.

There are other forces, like the weak and strong nuclear forces, but they primarily operate at the atomic level and are not generally considered non-contact forces in everyday scenarios.
