It seems like you're asking for two examples of contact forces. Here are two common ones:

* Friction: This force opposes motion between two surfaces in contact. You experience friction when you rub your hands together, push a box across the floor, or walk on the ground.

* Normal force: This is the force exerted by a surface perpendicular to the object in contact with it. For example, when you stand on the ground, the ground exerts an upward normal force on you, balancing your weight.
