Particle Physics Introduction: Fundamental Forces etc.

The Four Fundamental Forces

Strong Nuclear Force: 

• Strongest force (1)
• Very short range
• Holds nucleus together against enormous repulsion forces

Electromagnetic Force

• Second strongest force (1 / 137)
• Infinite Range
• Forces between charges and magnetic fields
• Leads to simple collisions between charged particles.

Weak Nuclear Force

• Third strongest force (10^-6)
• Involved in beta  decay

Gravitational Force

• Weakest Force
• …
