It is helpful to consider that some forces express themselves in what is called a field, and this field "surrounds" the object that has that force associated with it. We're familiar with a couple of the basic forces that do this, and gravity is one such force, while electromagnetic force is another. Let's look at them. If we consider gravity, it is reaching from the sun to all the planets (and other things in solar orbit) and is holding onto them. Earth is some 93 million miles from the sun, but the sun has held it in orbit for billions of years. Gravity can reach through the vacuum of space and grab a hold of things. It does, and we're glad for its effects. In electromagnetics, we see that the magnetic force reaching its invisible field lines out around the source to interact with ferromagnetic materials around it. If we have a sheet of glass, iron filings and a magnet, we can set up a demonstration. We can put the magnet below the sheet of glass to move the iron filings on the glass. The magnetic field (the field lines) will "reach through" the glass to interact with the iron filings, and we see the effects when we move the magnet. The forces are expressed in the field that is the "force carrier" of the "thing" that has the force associated with it. If we think of the "force field" around the object that has the force associated with it, then it is easier to see that the field can interact with other objects or materials. And it can do so without the object with which the force is associated having to be in contact with other objects on which the force is acting.
Drag is a noncontact force. It is a resistive force that acts on an object as it moves through a fluid, such as air or water. Drag force is dependent on an object's shape, size, and speed.
A noncontact force is a force that can act on an object without physically touching it, such as gravity or magnetic force. These forces can affect objects from a distance.
Yes, a magnetic force is a noncontact force because it can act on an object without physically touching it. Magnetic fields can exert forces on objects that have magnetic properties.
Yes. Gravity can be considered a noncontact force. There is no requirement of the force to touch the object which the force exerts itself on.
When you push against an object, the force you apply is called the applied force. This force is the external force exerted on the object by you pushing against it.

Universal gravitation.
contact
force can be classified as contact and noncontact
When you push against an object, the force you apply is called the applied force. This force is the external force exerted on the object by you pushing against it.
That simply means that it requires no contact between the objects to act.
The force is called the "contact force" or "normal force." It is the force exerted by a surface against an object that is in contact with it, pushing in the opposite direction of the external force applied to the object.
Force of Gravity.
The force that occurs when one object pushes against another object is called contact force. This force can be exerted through direct physical contact between the objects.
