Question

What are the four natural forces characteristics? What are the three types of fractions from greatest to least?

Answer 1

Hint: Force is described as an external cause that, when applied, affects or tends to modify the state of the body; if the body is in motion, it will come to rest, and if it is at rest, it will move. It can also induce changes in the body's orientation, shape, size, and other characteristics. Applying force to push or pull a door is an example.
And it is here that we shall learn everything there is to know about forces and frictions.

Complete step by step answer:
Physical forces are present in everything we do, from strolling down the street to launching a spacecraft into space to sticking a magnet on your refrigerator. All of the forces we meet on a daily basis (and many we aren't aware we encounter on a daily basis) can, however, be reduced to simply four fundamental forces.
The four fundamental forces of nature are:
1. Gravity: -
The attraction between two-mass or energy objects, such as a rock falling from a highway, planets circling, or the moon causing ocean tides, is known as gravity. The most natural and well-known of the fundamental forces is gravity, yet it's also one of the most difficult to comprehend.
Isaac Newton is said to have proposed the concept of gravity after witnessing an apple fall to the ground. He defined gravity as a physical attraction that exists between two objects. Hundreds of years later, Albert Einstein claimed that gravity is neither an attraction nor a force in his theory of general relativity.
2. Weak Nuclear Force: -
The weak force, often known as the weak nuclear force, is responsible for particle decay. This is the process by which one type of subatomic particle turns into another. If a neutrino gets too close to a neutron, the neutron may become a proton, while the neutrino remains an electron.
Physicists call this interaction the exchange of bosons, which are force-carrying particles. Different types of bosons are responsible for the weak, electromagnetic, and strong forces, respectively. W and Z bosons are charged particles that belong to the weak force. When subatomic particles such as protons, neutrons, and electrons come within 10-18 metres of each other, or 0.1 percent of the circle of a proton, these bosons can be exchanged. Subatomic particles decay and are replaced by new ones as a result of this.
3. Electromagnetic Force: -
The electromagnetic force, also known as the Lorentz force, is a force that exists between charged particles such as positively charged protons and negatively charged electrons. Charges that are similar repel each other, but charges that are diametrically opposed attract each other. The charge has a direct relationship with the force. This force, like gravity, can be felt from an indefinite distance. ṣ
As its name implies, the electromagnetic force is made up of two separate components: the electric force and the magnetic force. These forces were once assumed to be independent entities by physicists, but they were eventually discovered to be components of the same force. Whether charged particles are moving or not, the electric component acts within them, creating a field in which the charges can interact.
4. Strong Nuclear Force: -
The strong nuclear force, also known as the strong nuclear interaction, is the most powerful force in nature. It is evident from the definition of the strong nuclear force that it is far more powerful than gravity. This is due to the fact that it draws together the tiniest particles of matter in order to produce larger ones. The strong force brings the protons and neutrons of an atom's nucleus together and binds the quarks that make up protons and neutrons collectively.
Like the weak force, the strong force is only active when subatomic particles are extremely close to one another. They must be between 10 to 15 metres of one another, or around a proton's diameter. The strong force, unlike most of the other fundamental forces, weakens as subatomic particles grow closer together. It reaches its highest strength when the particles are the farthest apart from one another.
Now, let us learn about friction:
Frictional Force is the force created when two surfaces collide and slide against one another. The surface texture and the amount of effort required to bring them together have a big impact on these forces. The volume of frictional force is affected by the object's angle and position.
Friction is the force that opposes motion between any surfaces that are in contact with each other. Friction occurs between solid surfaces in the form of static, kinetic, sliding, and rolling friction.
All four types of friction are described below:
1. Static Friction: -
Before the box slips and moves, static friction occurs. The friction force in this location will be equivalent in magnitude and direction to the pushing force. The friction force increases in proportion to the degree of the pushing force. If the pushing force continues to increase, the box will finally start to slip. The type of friction resisting the motion of the box switches from static friction to kinetic friction when the box begins to slip. Impeding motion refers to the moment shortly before the box slips. This can also be regarded as the highest static friction force that exists prior to slippage. The maximal static friction force is equal to the static coefficient of friction multiplied by the normal force acting on the box and the surface.
2. Kinetic Friction: -
When the box is sliding, kinetic friction occurs beyond the point of coming motion. The quantity of friction force opposing motion with kinetic friction is equal to the kinetic coefficient of friction multiplied by the normal force between the box and the surface. The kinetic coefficient of friction is similarly determined by the two objects in contact, but it is nearly always less than the static coefficient.
3. Rolling Friction: -
When a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings, rolling friction occurs. The distribution of energy involved in twisting the items appears to be the main cause of friction in rolling. When a hard ball rolls on a level surface, it is considerably packed down, and the level surface is somewhat indented in the contact zones. The elastic bend or compression created at the leading section of the component in touch causes motion interference that is not fully compensated as the substances spring back to their original shape at the trailing section. Internal losses in both substances are similar to those that prevent a ball from returning to the level from where it was released. For similar materials, sliding friction coefficients are often 100 to 1,000 times greater than rolling friction coefficients.
4. Sliding Friction: -
Sliding friction is an opposing force that occurs when one thing slides across another. The following are some examples of sliding friction:
A lawn roller is being pushed across the grass.
Because of the sliding friction, rubbing one's hands together produces heat.
Sliding door/window is opened.
The mouse is dragged across the surface.
Making art on the floor with solid chalk.
Racing in high-powered automobiles.
We must understand that static friction is the most powerful frictional force, followed by sliding friction, and finally rolling friction.

Note:
Here we have differentiated forces on the basis of naturally occurring forces. We can differentiate on another basis too like:
On the basis of contact there are two types of forces,
Contact and non-contact.
1. Contact Force:
We only feel contact forces when two objects come into contact, as the name implies. Tensional forces, air resistance forces, and frictional forces are all examples of contact forces. The energy is transmitted from one object to another in contact forces. When an object is submerged in liquid, contact forces can be observed.
2. non-Contact force:
Non-contact forces occur when two objects are separated by a certain distance. The two items are never in close proximity to one another. Gravity is the most frequent non-contact force. It never comes into contact with the item, but it is always present and acting on it.
