Contact force is defined as the force that acts on an object through direct contact with another object. This force only occurs when two objects are in physical contact with each other and can result from various interactions, such as pushing, pulling, or friction. Conversely, non-contact force is the force that acts on an object without direct contact. These forces can influence an object from a distance and are based on fields like gravitational, magnetic, and electrical fields. Enroll now at Tutoroot.
