Fundamental forces
- The basic forms of interactions that can't be reduced further are called fundamental interactions or fundamental forces.
- These fundamental forces can be traced in nature and in many daily activities.
Gravitational Force
- Weakest fundamental force but has infinite range. This is an attractive force that acts between any two masses in the universe.
- It causes apples to fall from trees and determines the orbits of the planets around the Sun.
- As an application of gravity, we all are grounded to the earth.
Weak Nuclear Force
- The second weakest fundamental force comparatively has short-range.
- Radioactive decay and neutrino interactions are effects of this force.
- The force also causes the conversion of a neutron into a proton, an electron, and an antineutrino called Beta-decay.
Electromagnetic Force
- Stronger fundamental force, with infinite range. The force combines electricity with magnetism.
- It has range but is much weaker than the strong nuclear force.
- The force has attractive and repulsive acts between pieces of matter carrying an electrical charge.
- Like charges repel each other whereas unlike charges attract each other. Electricity, magnetism, and light are all produced by this force.
Strong Nuclear Force
- Strongest among four basic interactions but has a shorter range.
- The nucleus of all atoms has protons and neutrons. Neutrons have no electric charge whereas protons are positively charged.
- Even though protons are like charges that can repel, still they are in the nucleus by the strongest fundamental force.
- The force is 100 times stronger than the electromagnetic force that creates repulsion among protons to move apart.
- It is also strong enough to hold the quarks inside protons and neutrons together.
The strongest fundamental force is the strong nuclear force. This is a strong fundamental interaction that confines quarks into proton, neutron, and other hadron particles.
