Differentiate between Contact and Non-Contact Forces
By BYJU'S Exam Prep
Updated on: September 25th, 2023
Differences between contact and non-contact forces are listed below. As a characteristic of physical activity or movement, the force can be defined as a push or pull exerted on an item or energy. When two entities come into contact, this happens. Everything in this universe exerts a force on others in accordance with the universal law of gravity. The following parameter indicates the force exerted on an object:
- Symbol of Force: F
- SI unit of Force: newton(N) or kg.m/s2
- Dimensional Formula: M1L1T-2
- Type of quantity: Vector quantity
- Other units: dyne, kilopond, pound-force, kip, poundal
The body with mass m would be resting on top of the body with mass M, for instance, if there were two bodies of mass M and m. These two bodies will exert forces on one another, according to physics. Thus, the force can be said to be a component of any interaction involving two or more bodies.

Difference Between Contact and Non-Contact Forces
The differences between contact and non-contact forces are:
Contact force |
Non-contact force |
When two bodies physically touch, contact forces are created. |
There is no physical contact between the two bodies, thus the attraction or repulsion between them causes non-contact forces to develop. |
Contact force is not related to any field. |
The non-contact force has a field connected to it at all times. |
Frictional force, tension, and other types of force are contact force examples. |
The gravitational force, electrostatic force, and other non-contact forces are examples. |
Summary:
Differentiate between Contact and Non-Contact Forces
Contact forces are because of physical contact whereas non-contact forces are because of the attraction or repulsion between two bodies. Differences between contact and non-contact forces are listed above.
