Each in turn

Suggested: In physics, force is the perceptible cause of the acceleration of a mass (change in the rate or direction of its motion) and is experienced as a push or a pull. instead of In physics, force is what causes a mass to accelerate experienced as a push or a pull.
The addition of "and" is good. However, a force need not be "perceived" to exist. The definition of "acceleration" is indeed confusing to the lay person, but I think that the wikilink on acceleration covers it. We need to be careful to not go overboard in description in the lead.
Provide definition: "momentum (quantity of motion)"
Hmm, this isn't exactly an accurate definition of momentum since momentum is, in fact, both mass and motion. Again, the wikilink I think should suffice, but maybe we can reword things without providing definitions to make it clearer. I want this to be intelligible, but I'm afraid that including these points might be confusing for many and an annoyance to even more.
Following the development of quantum mechanics, it is now understood that momentum is a fundamental property of particles and that, according to the standard model of particle physics, changes in momentum are the consequence of the net emission or absorption by particles of momentum-carrying gauge bosons. Effects which are at the macro level experienced as a "force" are the consequence of the aggregate effect of these boson-mediated fundamental interactions. In modern physics, only four fundamental interactions are known; in order of decreasing strength, they are: strong, electromagnetic, weak, and gravitational.[1] High-energy particle physics observations in 1970s and 1980s confirmed that the weak and electromagnetic forces are expressions of a unified electroweak interaction. No gauge boson has yet been demonstrated for mediating the gravitational interaction and what is perceived as the "force" of gravity is more accurately attributable to the the effect of distortions by massive bodies of the curvature of spacetime as explicated in Einstein's Theory of General Relativity.
There is a slight issue here with the sentence: "Effects which are at the macro level experienced as a "force" are the consequence of the aggregate effect of these boson-mediated fundamental interactions." This sentence misses the fact that forces also exist on the micro level. A single boson-mediated fundamental interaction often has a "force" associated with it. For example, an electron accelerates because it emits a photon: this is due to the electromagnetic force acting on the electron. One micro-interaction: still a force since a mass accelerated.

I will implement the wording I think is good, but let's keep discussing the problematic wording.
