Contact Force vs. Field Force: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 12, 2023
Contact Force is a force applied through physical contact between objects. Field Force is a force exerted without physical contact, influenced by fields like gravitational, magnetic, or electric.

Key Differences

Contact Force refers to the force that occurs when two objects are in physical touch. It includes forces like friction and tension. Field Force operates over a distance without direct contact, examples being gravitational or magnetic forces.

The nature of Contact Force is such that it requires physical interaction between objects, such as pushing a cart. Field Force manifests through invisible fields and acts over distances, like the earth's gravitational pull on an apple.

Examples of Contact Force include the normal force from a surface or the force exerted while kicking a ball. In contrast, Field Force encompasses forces like the electric attraction or repulsion between charged particles.
