# Learn About The Hidden Forces That Explain Our Physical World

Hidden forces are all around us and play a big role in our physical world. These forces are not always obvious, but they are responsible for the way objects move and interact. The universe is a mysterious place. Even though we have learned a lot about it, there are still many unanswered questions. Scientists are constantly exploring new areas of the universe and uncovering new information. In this article, we will explore some of the hidden forces that help to explain our physical world.

## What Is A Force?

Force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons (N). The most familiar force is the gravitational force, which attracts objects due to their mass. Other forces include the electromagnetic force, which governs how charged particles interact, and the strong and weak nuclear forces, which govern the interactions of subatomic particles within atomic nuclei.

In everyday life, we experience only a handful of the many possible forces. For example, we feel the force of gravity when we stand on the Earth, and we feel the force of air resistance when we move through the air. We do not feel the other forces that are acting on us, such as the electromagnetic force or the nuclear forces. This is because these forces are either very weak or operate over very short distances.

## Types Of Forces

There are many types of forces. Some of them you are familiar with, such as the force of gravity that keeps you on the ground and the electromagnetic force that turns your lights on. But there are other, more hidden forces at work in our world too.

The four fundamental forces are Gravity, Electromagnetism, The Strong Nuclear Force, The Weak Nuclear Force. These forces are all constantly at work around us, and together they make up the hidden forces that explain our physical world.

### Gravity

Gravity is the force that attracts objects towards each other. It is what keeps us on the ground and causes things to fall. Gravity is a constant force that depends on the masses of the objects and the distance between them. With gravity, kinematic equations can be applied to fallen objects where air resistance is insignificant. It is described by the equation F=Gm1m2/r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. The force of gravity is proportional to the product of the masses and inversely proportional to the square of the distance.

### Electromagnetism

Electricity and magnetism are two aspects of electromagnetism. Electricity is the force that creates electric fields, while magnetism is the force that creates magnetic fields. Both forces are caused by the exchange of particles called photons. Electric fields are created when an electric charge is placed in a certain location. The strength of the field is determined by how much charge is present. Magnetic fields are created when electric current flows through a wire. The strength of the field is determined by the amount of current and the length of the wire.

An electric field can be used to deflect or move electric charges. A magnetic field can be used to deflect or move magnetic poles. Electromagnetic waves are created when an electric field and a magnetic field change with time.

### The Strong Nuclear Force

The strong nuclear force is one of the four fundamental forces of nature. It’s what holds together the nucleus of an atom. The strong nuclear force is attractive, meaning that it pulls particles together. But it’s also very short-ranged, which means it only affects particles that are close together. The strong nuclear force is much stronger than the electrostatic force, which is what holds electrons in orbit around the nucleus. The strong nuclear force is mediated by particles called gluons. Gluons are bosons, meaning that they have integer spin. They’re also massless, which means that they travel at the speed of light.

### The Weak Nuclear Force

The weak nuclear force is one of the four fundamental forces of nature. It is responsible for radioactive decay, which is the process by which an unstable atom breaks down into a more stable form. The weak force is mediated by particles called bosons. These particles are exchanged between particles that interact with each other via force. The most well-known boson associated with the weak force is the W-boson.

In conclusion,  the hidden forces that explain our physical world play an important role in our lives. They help us to understand how the world works and why things happen the way they do. By learning about these hidden forces, we can better appreciate the world around us and the laws that govern it.
