What are 5 examples of contact force?
A force that can cause or change the motion of an object by touching it is called Contact Force. For example, muscular force,frictional force,spring force,tension force,air resistance force etc.
fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.
There are three types of contact force namely frictional force, applied force and normal force.
These are those types of forces when two objects interact with each other; they have a physical contact with each other. Types of contact forces are: Frictional force; Tension force; Normal Force; Air Resistance Force, Applied Force, Spring Force.
Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
Abstract It is known that there are exactly four fundamental forces of nature: gravity forces, forces corresponding to weak interactions, electromagnetic forces, and forces corresponding to strong interactions.
The universe is governed by four fundamental forces: gravity, electromagnetism and the strong and weak nuclear forces. These forces drive the motion and behavior of everything we see around us. At least, that's what we think.
Gravitational force is an example of a non-contact force.
- Gravitational force.
- Electromagnetic force.
- Strong Nuclear force.
- Weak Nuclear force.
Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction force.
What is 4 state the difference between contact force and non contact force?
| Contact force | Non-contact Force |
|---|---|
| 1. Contact forces arise due to physical contact between two bodies. | 1. Non-contact forces arise due to attraction or repulsion between two bodies, i.e, there is no physical contact between them. |
Out of the given forces, electrostatic force and Gravity don't require any contact to show their effect. Hence they are non-contact forces.
Some examples for contact forces are a person throwing a ball or writing on paper. The contact forces are push, pull and friction. Some examples for non- contact forces are a magnet and a paperclip and the moon's gravity and the earth's tides. The two non- contact forces are magnetism and gravity.
Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.
Muscular forces is an example of contact force.
