1. Exchange particles
And you

2. What is an “Exchange Force”?
Great question-
It is a force that exists due to an interaction of force carrier particles
A constant exchange of particles that results in the transmission of force.
Attractive, repulsive, limited by distance, unlimited by distance…
Parallel to sitting on the carts and tossing a heavy backpack up and back...

3. What types of particles exist?
All the types necessary to account for the fundamental forces of the universe
Strong F: Gluons
EM F: Photons
Weak F: Bosons
Gravitational F: Gravitrons

4. The Strong Force: Gluons
“glue” quarks together to form nuclides – and extends beyond to nuclide interactions
Zero mass
8 types (colors) with color charge
Confined within composite particles “Hadrons”
Very short range ~ 10E -15 m
Exotic particles made up of nothing but gluons are called “glue balls”

5. Electromagnetic force: Photons
Infinite range
Zero rest mass
Deflection by gravity

6. The weak Force: W and Z Bosons
Responsible for the decay of the neutron and beta decay
Involved in the transformation of quarks

8. Gravitation force : Gravitons
Infinite range
Massless
Gravitatonal waves are collections of gravitons
