# 11 different types of force In physics, force can be defined as a thrust or thrust to any object that has mass, which changes the movement of the object.

In other words, force forces an object with a mass to change its direction and velocity.

Two great physicists, Isaac Newton and Galileo Galileo, described the behavior of the forces mathematically. In 1638, Galileo experimented on an inclined plane that revolutionized the way in which power was measured. Five decades later, Newton developed the laws of motion that laid the foundation for classical mechanics.

Because the force has both the size and the direction, it is a vector value. It is represented by the symbol F and measured in the unit SI Newton.

The force can be divided into two groups depending on its use:

To better explain this phenomenon, we have described all the different types of forces by way of examples. Let's start with four fundamental forces in nature.

## 1. Gravity force

Type: no contact force

Gravity power is what attracts two objects with mass, and it acts on every object, including you, in the universe.

The gravity force of objects on each other "is directly proportional to the work of their masses and is inversely proportional to the square of the distance between them." The larger the objects and the smaller the distance between them, the higher the force.

It is the weakest of the four fundamental forces found in nature.

Although gravity does not have a significant impact on subatomic scales, it is the dominant interaction on macroscopic scales and has a significant impact on the formation, structure and trajectory of celestial bodies.

Example: Gravity causes an apple to fall from a tree; it causes the moon to rotate around the Earth; it holds off the gases on the sun.

## 2. Electromagnetic force

Type: Incompatible force

It's a kind of interaction that happens between electrically charged particles. Electromagnetic fields carry electromagnetic power.

Electricity and magnetism are linked: current electrons create magnetism, and moving magnets generate electricity. The relationship between them is very well explained and quantified by James Clare McSwell.

Example: The most common example of electromagnetism is light, as it spreads in space, carrying the energy of electromagnetic radiation.

The next most common example is the forces between electrically charged atomic nuclei and electrons of atoms.

## 3. Strong nuclear force

Type: Incompatible force

In nuclear physics and particle physics, a strong interaction is responsible for the structural integrity of atomic nuclei. Since all protons have a positive charge, they repel each other. A strong nuclear interaction keeps these repulsive protons together, so they can form an atomic core.

About 99% of the mass of neutron or proton is the result of energy from a strong force field.

It is the strongest force in nature, operating at a distance of one femtometer, once more than the force of gravity.

Example: A strong nuclear force connects quarks to Hadron particles such as proton and neutron to create a nuclear core, a force that connects normal matter.

On a wider scale, it is used in nuclear power plants to produce heat for the purpose of generating electricity, and it is also responsible for the enormous destructive power of nuclear weapons, and because of this power, nuclear weapons release an extreme amount of energy in an explosion.

## 4. Weak nuclear power

Type: Incompatible force

In nuclear physics, weak interaction refers to the interaction between subatomic particles, which causes radioactive degradation of atoms; more specifically, it is responsible for the break-up of some nucleons into leptons and other types of Hadrons.

Its field tension is about 1013 times smaller than that of a strong nuclear force, yet it is much stronger than the gravitational force at short distances.

Example: The most known effect of low-power action is beta degradation and associated radioactivity, which occurs in several different reactions, including solar burning and radiocarbon dating.

It's four fundamental forces that make everything else happen, they support the burning of the stars and the spinning of the planets, without them the universe we know wouldn't exist, and even if it existed, it would be a completely different place.

Let us now turn to the non-core forces that arise from the direct physical interaction between the two objects.

## 5. Applied force

Type: Contact force

As you can see from the name, this is the force that you apply to the object. The object starts to move when the force is overcoming the inertia of the object.

The body shall remain at rest or in uniform motion on a straight line unless accompanied by an external force which alters the state of motion and direction of the body. The acceleration of the body is directly proportional to the force applied.

Example: Force attached to the box by man.

## 6. Friction force

Type: Contact force

The surface force opposing the relative movement of the body is called the friction force. Since no object is perfectly smooth in the real world, there is always some friction between the two surfaces. It is proportional to the coefficient of friction of the surface material.

The two main types of friction forces are static . Air resistance is also a friction force that operates on objects when they move by air.

It always operates in the opposite direction and converts kinetic energy into thermal energy. ) In general, friction is a critical and desirable force that provides adhesion to facilitate movement over land.

Example: An example of friction is the slipping of cabotage on the table, the slipping of two cards in the well against each other, and the friction of a hand to generate heat.

## 7. Normal force

Type: Contact force

When two surfaces are in contact, they have a normal effect on each other. The term "normal" refers to perpendicular. This means that the force is directed perpendicularly to two contact surfaces.

For example, when the laptop is on the table, the normal force keeps it from falling over the table. The gravity of the Earth pulls the laptop down, but since it doesn't actually fall, there has to be a force constantly pushing it up. That's what we call normal force.

It comes from the electromagnetic force: the electrons of the laptop push the electrons of the table. Because all the electrons are not charged, they don't get much closer to each other, and the laptop is based on the top of the table.

## 8. Tightening force

Type: The force of tension shall normally be transmitted through a wire, cable, string or rope when it is tightly coupled by forces operating at opposite ends. The force shall be directed along the length of the cable.

The tension can also be defined as the reaction of a pair of forces at each end of the cable, which is the opposite of compression.

Example: A rope pulling a box or a box hanging on a rope would be a great example of tension.

## 9. Tensile force

Type: Contact force

The force of turgidity is the force applied by a tensioned or compressed string to the object to which it is attached.

The spring ' s ability to resist distortion and return to the initial state of exposure depends on its material, the number of turns and the diameter of the wire forming the turn. These characteristics are generally quantified in a parameter called permanent spring "k".

For all springs subject to the law of Guk, the force is directly proportional to the permanent spring.

Example: Vehicle absorbers are made of springs and are designed to absorb shock pulses by converting kinetic impact energy into another form of energy that is then dispersed.

## 10. Central forces

Type: Incompatible force

The centrifugal force operates on objects that accelerate in circular motion, which is the force that forces the object to follow a curved path.

The direction of this force is always directed to a fixed point of the instantaneous centre of curvature of the trajectory and orthogonal movement of the object.

Example: The two most common examples of centrifugal force are the rotation of the car and the Earth around the sun; in the first case, the centrifugal force is generated by friction between the wheels and the ground, and in the second, by gravity.

## 11. Inertia force

Type: Incompatible force

Inertia force is clear from the mass forces described by the non-inertial reference system, including the rotating reference system.

This comes into effect when the reference system begins acceleration. The term "inertial force" has an exact meaning for Newton mechanics; in fact, it is always proportional to the mass of the object on which it operates.

Example: The forces you experience in a moving car are everyday examples of inertia. When a car moves forward, it pushes you back into the seat. When a car makes sharp turns, it throws you from side to side. These influences arise because the natural reference system for the situation itself accelerates.
