Final answer:
Gravitational force and electromagnetic force are two types of forces that can act between two objects without physical contact.
Step-by-step explanation:
In physics, there are two types of force that can act between two objects without physical contact: gravitational force and electromagnetic force.
Gravitational force is the force of attraction between two objects due to their masses. For example, the gravitational force between the Earth and a person causes the person to have weight.
Electromagnetic force is the force between charged objects. It includes forces like the pull of a magnet and the repulsion between two negatively charged objects.
