Non-Contact Force

The forces which are applied to other objects without any physical touching are called non-contact forces. 

Examples of non-contact forces are magnetic force, electrostatic force, and gravitational force. Now let’s discuss types of non-contact force in detail.

Magnetic Force

Magnetic force is a non-contact force exerted by a magnet on any other magnetic substance. For example, if we bring a magnet near an iron nail then the magnet pulls them towards it since magnets exert force.

Electrostatic Force

An electrostatic force is a non-contact force that can be exerted by a charged object on another object from a distance. For example, when a plastic comb is rubbed in dry hair, then the electrically charged comb attracts a tiny piece of papers

Gravitational Force

The Gravitational force is a non-contact force between two bodies having some mass. It is an attractive force. The force of attraction between the earth and any object is called the force of gravity.

Force

Force is defined as an external cause that a body experiences as a result of interacting with another body. Whenever two objects interact, a force is exerted on each object. 

In general-term “To Push or Pull an Object” is defined as the force. The force is the interaction experience by the object because of the other object. Generally, force applied to an object changes its state of rest or motion and it also adds acceleration to the object. 

Let’s learn more about force, its unit, and others in detail in this article.

What is Force?

A push and pull of an object are referred to as a force in science. Force is created when two things interact. The force is a vector quantity as it has both magnitude and direction. The magnitude of a force is represent its strength. The force can also cause a change in direction of the body to which the force is applied....

Unit of Force

Force is a vector quantity, this implies it has both mass and magnitude. The force acting on an object is represented by the symbol F or [Tex]\vec F   [/Tex].The SI unit of force is Newton (N). It is named after the famous English scientist Sir Issac Newton. 1-Newton force is defined as the force required to accelerate a mass of 1 kg by 1 m/s2 in the direction of applied force.In the CGS system, the unit of force is Dyne....

Force Formulas

Force is defined by the product of the mass and acceleration of the object. For a body with mass “m” and the acceleration “a” the force can be calculated as,...

Magnitude and Direction of Force

To move a large weight, the individual must pull or push it in the same direction. When two individuals push or pull weight in opposite directions, the resultant force is the sum of the two forces. The magnitude of a force expresses its strength. When forces are applied in the opposite direction, the size of the resultant force is reduced....

Types of Force

A Force can act on an object with or without any contact. For example, if you are pushing or pulling a door then you must have contact with a door while if you have a bar magnet you can easily attract iron nails without having any contact with the nail. So in science, we have two types of forces, one is a contact force and the other is a non-contact force....
