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.
Force can be both contact or non-contact
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.
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.
Electrostatic Force are non-contact force.
