A contact force is any force that occurs as a result of two objects making contact with each other. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car or kicking a ball are some of the everyday examples where contact forces are at work.
As the name suggests, the forces that act between two bodies that are not in contact with each other are called ‘non-contact’ forces. These forces act between two bodies that are not physically touching each other.
The microscopic origin of contact forces is diverse. Normal force is directly a result of Pauli exclusion principle and not a true force per se: Everyday objects do not actually touch each other; rather, contact forces are the result of the interactions of the electrons at or near the surfaces of the objects.
As the name suggests, these forces act between the objects in close contact with each other. It acts at the point of direct contact between the two surfaces. Newton’s laws of motion govern contact forces. These are present everywhere, and most of the macroscopic interaction between two objects can be attributed to these forces.
