Bet that slug didn't move at the speed of light.

Well, neither does this one... but you still dont want to be hit by it;

Why doesn't the AC20 or Gauss knock a Light mech over when it connects?

Because the game isn't balanced.

"I don't always shoot an Alpha, but when I do, it knocks the target off its feet."

I would say its because the game IS balanced. In TT 20 points of damage or more forces a piloting check to prevent mech from falling regardless of size . Having High damage weapon knock down lights but not other mechs would unbalanced.

Fun fact: The word "Gauss" is spelled wrong ("Guass") in 1 in 10 cases on this forum.

Fun fact: A Gauss is a non SI unit of electrical field measurement (1 Gauss is 1/25th the Earth's magnetic field at the Earth's core). Gauss is also the last name of Carl Friedrich Gauss, who contributed to many scientific theories.

as BattleMech armor is apparently made of layered composite materials I doubt the effect would be as pictured

Newtons third law of motion suggests that for every action there is an equal and opposite reaction, so if there was sufficient force to knock over 35 tones with a center mass hit it would mean:

1) a light Mech would also be knocked over by the recoil when firing Gauss rifle or AC20

2) any Mech 70 tons or less with a high mounted AC20 or Gauss Rifle (e.g. Hunchback, Jagermech) would be knocked over when firing

3) any Mech would loose balance if firing a Gauss Rifle or AC20 when airborne

4) even an Atlas with both feat planted firmly on the ground would suffer severe recoil, possible be pushed back a few meters or suffer severe torso twist from the recoil

5) those affects would have to be scaled for all ACs and Missiles, rendering Ballistic and Missile boats useless.

6) the above would end the AC/PPC meta, likely replacing it with a PPC only meta, that could be a good thing

edit: spelling

When firing a Gaussrifle the counterforce is of magnetic nature.
There is no propelant involved.
There are two possible kinds of Gaussrifles:
  • A Ferromagnetic Gaussrifle works with an magnetic coil in front of the projectile. The magnetic coil is switched on until the projectile has reached the point where the magnetic field changes its polarisation. Then it is switched off and the Projectile continues to shoot out of the coil.
  • A Induction Gaussrifle has the magnetic coil behind the projectile and it generates a magnetic field that pushes, rather than pulls, the projectile out of the barrel. This is done with materials that are only magnetic when electrically charged.
Both kinds achieve the accelleration of the projectile with magnetic fields and therefore are free of recoil.

I am sorry, bit it does not matter -how- you propel the slug, there is recoil. That is due to the imparted force to the slug imparting the opposite force (not speed!) to the firing weapon. As long as you are unable to transform that Energy into some other form (like heat) you get the recoil, there is no other way around this!
In fact, real life personal carried "gauss rifles" would be no more effective than current rifles due to that very fact, even if power supply issues can be solved. (Apart, of course, in special cases e.g. where subsonic slugs can be really silent)

As for the knock over thing: It is a function of
A) How much of the kinetic energy is transferred into momentum of the mech. (A large part of the momentum might be transformed into heat on impact, or deformation of the target material. Think Formula 1 cars disintegrating on impact and thus transforming that energy, so the driver isnt killed due to rapid deceleration.
;) You can reduce the force on the firing mech by recoil compensation (A Spring reduces peak force against having longer to deal with the force, or some form of producing a counterforce)

This means a Mech might succesfully fire a Gauss Rifle with seems to have little recoil (though it definitely has!) and still knock over some mechs or,
on the other hand mech armor is described as ablative in natur which transforms the impact energy, leading to imparted momentum, so the felt recoil might actually be higher for the attacker than for the victim.

Gamewise i'd like to have heavy recoil on Ac's and Gauss Rifles =)

Wile neither use a propellant to accelerate the munition, the munition still has a mass that the magnet has pull. And it would be this mass that would equally pull on the coil creating recoil.

The firing of any gun, electromagnetic or otherwise, imparts substantial momentum to the launcher, and ultimately the weapon platform. The objectives of the future combat system program call for similar lethality to a current heavy tank on an extremely lightweight vehicle of nominally twenty tons. Prior experience with the M551 Sheridan, a light tank first put into production by the United States in 1966, raises concern that firing large caliber armaments from light vehicles may result in unacceptable crew discomfort and vehicular reaction during recoil. It is the purpose of this paper to provide a future combat system armament integration perspective for railgun recoil

Actually the recoil force can be used to propel a spaceship. There has been real research into this (Though there are too many drawbacks for that kind of aplication).

Oh, that old chestnut. Only true if the gun designer is a complete moron.
