3. Known to experience the same
gravitational acceleration as other
particles (which provides empirical
evidence for the equivalence
principle) because they do
have relativistic mass, which is
what acts as the gravity charge
moves in straight lines in
spacetime, called geodesics
6. carrier of
the strong force
Particle that
carries the force
between quarks
massless bosons
mediate the
strong color force
between quarks
7.
8. massless tensor bosons
A massless spin-2 particle
which is the hypothetical
quantum of the gravitational
field
9. A hypothetical elementary
particle associated with the
gravitational interaction
A stable particle with zero rest
mass, zero charge, and a spin
of ± 2, and travels with the
speed of light
10.
11. “Ghostly Particle”
An electrically neutral, very weakly
interacting particle, with a rest energy
which is either zero or very small
A stable particle with no charge, a rest
mass of zero, and a spin of 1/2, that
carries away energy in the course of
nuclear reactions
Its main characteristic is the weakness of
its interactions with all other particles
12.
13. carrier of electromagnetism
Smallest packet of the
electromagnetic force field
messenger particle of the
electromagnetic force
smallest bundle of light
14. mediate the electromagnetic force
between charged particles
can also adopt a mass for a short
period, in accordance with
Heisenberg's uncertainty principle
A transverse wave of electric and
magnetic fields which can
propagate through empty space.
