Fundamental forces are really important because they control how tiny particles behave. There are four main forces we should know about:

1. Gravitational Force:

   • This is the weakest force.
   • It's about 10 billion trillion times weaker than the strong force!
   • Gravitational force pulls things together, like how the Earth pulls us down.

2. Electromagnetic Force:

   • This force happens between particles that have an electric charge.
   • It works with tiny particles called photons.
   • It's super strong, about a billion trillion times stronger than gravity!

3. Weak Nuclear Force:

   • This force helps particles change and is involved in something called beta decay.
   • It works on a very tiny scale, much smaller than a proton.

4. Strong Nuclear Force:

   • This force holds protons and neutrons together inside atoms.
   • It's really powerful—about 100 times stronger than the electromagnetic force, but only over very short distances.

These four forces play a big role in how matter behaves and stays stable in our universe.
