It's impossible to name just two forces that act on objects because there are many forces in physics. However, I can provide you with two very common and fundamental forces:

1. 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.

2. Electromagnetism: This force governs the interaction of electrically charged objects. It includes things like the attraction between opposite charges (like a magnet and a piece of metal) and the repulsion between like charges. Electromagnetism is responsible for many everyday phenomena, such as electricity and light.

These are just two examples. Other forces include:

* Strong Nuclear Force: This force holds the nucleus of an atom together.

* Weak Nuclear Force: This force is involved in radioactive decay.

* Contact Forces: These forces result from direct contact between objects, like friction or the normal force.
