A force that does not require contact is an example of:

A force that does not require contact is categorized as a non-contact force. Non-contact forces can act over a distance without the need for physical interaction between objects. Common examples include gravitational force, magnetic force, and electrostatic force. These forces influence objects through the field they generate, allowing them to exert an influence without touching.

In contrast, static force, dynamic force, and frictional force all involve direct physical interaction. Static force pertains to objects at rest experiencing forces that keep them stationary. Dynamic force relates to moving objects, while frictional force is the resistance encountered when two surfaces are in contact. These types of forces rely on the presence of physical contact between the objects, distinguishing them from non-contact forces.
