FOUR BASIC FORCES IN NATURE

FORCEFor an object to move, force is

needed. It is simply defined as a

push or pull. More so, it gives energy to

an object.

 Particle Physics - Forces, 1 of 2 

In chemistry, the reason we could study how materials behave is because they exist, holding together by some kind of forces.

In fact all known forces (or interactions) in the universe can be grouped into four basic types. Below lists these forces in the order of decreasing strength.

1. The Strong Force

This force is responsible for binding of nuclei. It is the dominant one in reactions and decays of most of the fundamental particles. This force is so strong that it binds and stabilize the protons of similar charges within a nucleus. However, it is very short range. No such force will be felt beyond the order of 1 fm (femtometer or 10-15 m).

This acts between electrically charged particles. Electricity, magnetism, and light are all produced by this force and it also has infinite range.

This is the force which exists between all particles which have an electric charge.

. This is originated from the fact that no two atoms can occupy the same space. However, its strength is about 100 times weaker within the range of 1 fm, where the strong force dominates.

Act on electrical charges and make it possible for power plants to produce electricity and motors to move.

2. The Electromagnetic Force

3. The Weak Force

 This force is responsible for nuclear beta decay and other similar decay processes involving fundamental particles. The range of this force is smaller than 1 fm

and is 10-7 weaker than the strong force. Nevertheless, it is important in understanding

the behavior of fundamental particles.*the most elementary particles are acted upon by weak forces

4. The Gravitational Force

This is the force that holds us onto the Earth. It could be important in our daily life, but on the scale of atomic world it is of negligible or no importance at all.

* Gravitational force is cumulative and extended to infinity.

.

*This force acts between all mass in the universe and it has infinite range.

*All these natural forces play the same role as the others, it accelerates something that is sensitive to it.
