Noncontact force

A non-contact force is one that works on an object without actually coming into touch with it. Gravity, which provides weight, is the most well-known non-contact force. A contact force, on the other hand, is a force that acts on an object that comes into actual touch with it. Any load acts on an object by another body without making touch is referred to as non-contact force. Noncontact forces include gravitational force, electrostatic force, magnetic force, and electrochemical force.

Contact Force

A contact force is that can only be activated when two bodies are in physical contact. As we know from the second law of motion of Newton, it asserts that exerting force on a mass of m causes it to accelerate.

Suppose we have body having mass m and acceleration that it achieves is a, the force exerted on body is given as:             F=ma

When we apply force to a body, it creates momentum, which results in a rate of change in momentum equal to the applied force.

The momentum will be given as:   F= Pt

Types of contact forces:

• The resistance of the air tension on the surface
• Friction
• Upthrust or buoyancy force
• Dragging force
• Nature’s forces
• Muscle strength

Examples of Contact Force

A football is thrown into the air and flies to the ground. This graphic depicts two types of forces. As a result of our kick’s contact force, the ball first performs a vertical motion, then a projectile motion, and finally, as an outcome of air resistance or simple friction, the ball falls down and ultimately comes to rest, i.e. on field.

When a spring is extended from its resting state, it starts to oscillate from its mean position. The spring, on the other hand, due to the influence of restoring force, returns to its original position after a period of time.

Non-Contact Forces

The noncontact forces are given as:

Gravitational force, (electric force Plus magnetic force) Force of magnetism.

In contact force, the forces are unseen to the naked eye and can act without the need for physical exertion. Vector fields cannot be used to depict non-contact forces. The non-contact force is related with the help of a field. A ball in the sky will eventually descend to the ground due to gravity’s action. You’ll see that when you shift the direction of one of the magnets, they attract each other.

Without coming into direct physical contact with one another, a non-contact force occurs between two bodies. Despite their separation, the two bodies are subjected to push and pull pressures.  Action-at-a-distance forces include gravitational forces. The sun and planets, for example, have a gravitational pull on each other despite their immense distance.

Even after your feet leave the ground and you are no longer in physical contact with it, there is a gravitational force between you and the Earth.

Forces that act at a distance are known as electric forces.

Protons in an atom’s nucleus and electrons outside the nucleus have an electrical attraction to each other, despite their minimal spatial separation.

Magnetic forces are forces that act at a distance. Two magnets separated by merely a few millimetres, for example, can exert a magnetic force on each other. 

Types of Non-Contact Force

A force that is act on object without making physical contact with it is referred to as a “non-contact force.” is, in other words, a force that operates at a distance. There is always a gap between the two interacting bodies.

Gravitational force

The gravitational force is a gravitational attraction that exists between any two mass-bearing things.

The gravitational attraction of the sun, which exists between all substances with mass and keeps the sun and the other planets of the solar system in a constant orbit, will be this force. It is not essential to make contact with gravity to extract its downward force. The non-contact gravitational force has a number of advantages, including the fact that it is a continuous force that keeps things in place. Our muscles and bones are kept active by gravity, and the planet’s atmosphere is maintained by gravity. 

Magnet force 

A magnetic force is the force exerted by magnetic materials on other magnets or metal objects.

Moving charged particles can exert magnetic force. The magnetic force in nature can be either a pull or a push. Tesla are the units of measurement for magnetic force.

Electrostatic force

Electrostatic force is the force that exists between two charged items. It can be both alluring and repellent in nature. Positive and negative charges resist one another, whereas positive and negative charges interact.

Conclusion

A non-contact force is one that works on an object without actually coming into touch with it. A contact force is that can only be activated when two bodies are in physical contact.  the force exerted on body is given as:  F=ma. The noncontact forces are given as: Gravitational force (electric force Plus magnetic force) Force of magnetism. A “non-contact force” is a force that acts on an object without making physical contact with it. It is, in other words, a force that operates at a distance. Electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays, and gamma rays are all examples of this force. The gravitational force is a gravitational attraction that exists between any two mass-bearing things.
