#1489: Fundamental Forces explain

Fundamental Forces

[Cueball is holding his hands up while giving a lecture to an off panel audience.]

Cueball: There are four fundamental forces between particles:

(1) Gravity, which obeys this inverse square law:

Fgravity = G m1m2/d2

Off panel audience: OK…

[Cueball is still holding his hands up while continues the lecture to the off panel audience.]

Cueball: (2) Electromagnetism, which obeys this inverse-square law:

Fstatic = Ke q1q2/d2

…and also Maxwell’s equations

Off panel audience: Also what?

[Zoom in on Cueball as he continues the lecture to the off panel audience.]

Cueball: (3) The strong nuclear force, which obeys, uh …

…well, umm…

…it holds protons and neutrons together.

Off panel audience: I see.

Cueball: It’s strong.

[Cueball finishes the lecture to the off panel audience and spreads out his arm for the final remark.]

Cueball: And (4) the weak force. It [mumble mumble] radioactive decay [mumble mumble]

Off panel audience: That’s not a sentence. You just said “Radio-

Cueball: – And those are the four fundamental forces!
