Because gravity can pull on stuff without touching it. Ocean tides are caused by the Moon's gravity pulling on the water, and that sure isn't touching.
Gravitation is a non-contact force because it does not require direct physical contact between objects to act on them. Objects can exert a gravitational force on each other even when they are not in direct contact, which is why it is considered a non-contact force.

Yes, wind is a non-contact force because it does not require physical contact to exert a force on an object. Wind can push or pull objects without direct contact, making it an example of a non-contact force.

A non-contact force is any force applied to an object by another body that is not in direct contact with it. The most common example of a non-contact force is gravity. A non-contact force is different from a contact force, which is a force applied to a body by another body that is in contact with it. However it is to be noted that the origin of all contact forces can be traced to non-contact forcesIn physics, a contact force is a force between two objects (or an object and a surface) that are in contact with each other. This is distinct from a non-contact force, or action-at-a-distance force (a force that acts over a distance), such as gravity or magnetic attraction/repulsion.
One example of a non-contact force is gravitational force, which acts between objects without direct physical contact between them. This force is responsible for the attraction between all objects with mass in the universe.
A driving force can be both contact and non-contact. For example, a contact driving force could be the friction between a car's tires and the road that allows it to move forward. A non-contact driving force could be the gravitational pull of the Earth that keeps a satellite in orbit.
Force can be both contact or non-contact
Electrostatic Force are non-contact force.
No, wind resistance is an example of a non-contact force, as it acts on an object without physical contact. Contact forces, on the other hand, require direct contact between objects for the force to be applied.
