Reply to comment by Any_Branch_4379 in ELI5: why can’t someone who is light in weight punch as hard as someone who is heavier? by Any_Branch_4379
I'm not entirely sure what you mean by 'whipping' a punch. So I'll just go with what I know. There are 5 basic punches and the rest are just variations on them. Jab, Cross, Hook, uppercut, and overhand. Each of these punches is not just a different arm movement, but a different series of body movements. If we compare a jab and a weak side hook for example.
Jab: starts in the toes, and rear thigh, tensing those to give a rock solid base. Let the flex radiate upward to your core as you exhale sharply involving your abs and diaphram. Rotate your wrist as quickly as you can to unfold your arm straight out. You want your fist to impact at the exact moment that you fully clench your fist, the exhale completes and you flex your rear knee. Keep your center of balance directly under your shoulders the entire time, do not shift into putting more than 30% of your weight on your front leg. Your aim point should be about three inches behind the contact point. As soon as you make contact counter rotate your wrist to bring your arm back to your guard. This punch should be as fast and crisp as possible. You typically aren't looking for a knockout with a jab, you just want to take a small opening and wedge it open for a bigger punch.
Hook: From your back leg shift your weight from sode to side to your front leg. Load your front leg and prepare to drive back to the side that your weight just came from. This punch is all ass and obliques. Exhale sharply as you tilt your elbow to aim. Come across with your fist as hard and sharply as you can. Fully clench your fist and finish your exhale as you make contact. You want to drive this punch through something, I like to aim for putting the punch into the inside opposite wall of my opponents skull if I aim for the head and I want to drive it to the spine if I aim for the body. At the point of impact your entire body should be a wall of flexed muscle. Recover by twisting your elbow back into place for your guard.
In either punch you want to make an imaginary box, the top is your eyes, the bottom is your floating ribs, and the sides are the tips of your clavicle. This box extends out from your chest. Your hands do not leave this box. They are stuck in the box. We aren't getting fancy here, your hands stay in the box. And breathe dammit.

Wow, just wow. With all these bodily movements involved in a simple variation of a punch, it makes me just wonder and appreciate how these fighters are able to just ‘do them’ as though they were second nature.
What I meant by “whipping a punch” was basically involving your shoulders in the punching motion. Snapping your shoulders like a whip as you’re extending your arm to punch seems to also give it more force. That’s what I was told

they're not able to do them by second nature. they've had to throw the same punches thousands of times since they were little kids to develop the technique they have. it's their job to be able to punch well. practice makes them good.
what you're talking about when you say whipping the punch to make it harder is basically just saying throwing it faster to make it hit harder, which is true. force = mass x acceleration and velocity is a component of acceleration. if you throw the punch with higher velocity, you're making one of the numbers you have to multiply to get your force output bigger, which makes the force itself bigger.

This is a good start to thinking about fight physics, another thing from physics that you have to think about while training are Newton's laws of motion. The third comes up a lot for a strike.
If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.
So I need my body to be a wall at the moment of impact, any give in me is less force that they have to take. So if I throw a hook, and do it with just my arm, and my feet arent set, my core and ass arent fully engaged and/or my legs are wobbly, then Im going to move and that will lessen the impact on my opponent.

The whole body should be involved, toes to knuckles. A proper punch or kick involves almost every muscle in the body, even the ones in the non-striking arm or leg. That's why proper technique has a twisting motion to the hips; you add the momentum of the entire upper body, not just the arm reaching out to strike. In my experience, setting the upper back solid when striking seems to make the biggest difference in the amount of force delivered as it provides a kind of backstop to the shoulder as the force of the strike is being transferred. If you don't keep your shoulders solid, and have good arm alignment when you strike, the force generated by your legs and hips goes into bending your wrist or shoulder instead of transferring into your target.
Wrist rotation is not 100% necessary; it's a technique I've encountered in some martial arts and ignored in others with no discernable difference in speed or power. I've personally had better results not rotating the wrist as I seem to have better alignment without rotation, but that may be a practice thing. It's also easier to get boxer fractures of the ring & pinky knuckle with a horizontal fist than it is with vertical or slightly angled fist. The slight gain of the twist (which is in itself debatable) is easily offset by having good alignment of the bones when striking.
