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 (a force that acts over a distance), such as gravity or magnetic attraction/repulsion. An example of contact force commonly encountered in college-level physics is the force between two masses A and B which are lying next to each other and a force F is being applied on one of the masses, for example A. In such a case, the contact force will be proportional to the mass of B.

A contact force is a force between two objects that are in contact with one another. This is the opposite of field force. This means that they dont have physical contact.

It is a force between two objects. An example of this is a baseball bat hitting a ball. Another example is a boxer hitting his opponent.

Contact force is the force between 2 objects that are in contact with one another. For example a ball hitting another ball. This is the opposite of a non-contact force or a field force. They both are apposing force on objects.
