    Anyone have a link to the video? All I’m able to dig up is that dude throwing a can at some cops and getting spear-tackled by a bootlicker.

    If a bat is coming towards you, ducking might not be the best approach…

      moving away is exactly the best approach, as it lessens the force of the impact. not to mention they are wearing a backpack, which might be able to fully absorb the impact of a baton depending on the contents.

        No. Moving away is only ok if you really put some distance between the two, otherwise you’re still within reach – it’s a baton, not a fist or knife.

          moving away by any amount lessens the force of the blow. this is elementary level physics, and your arguing it really shows the sorry state of American education.

            In this specific case it’s better to move in. Even better if the fist ends past your back.

            No, you’re flat out wrong, the bat is moving in a rotational motion and increasing in speed as it rotates because the wielder won’t be putting any stopping force until they are past the point they intend to strike. This rotational motion, where the farthest point from the fulcrum (shoulder) has the most force. Meaning if you are in range, the farther out you are, the harder you get hit. You must be able to get out of range in order for backing away to be effective, otherwise you get hit harder.

            You’re only correct if it’s thrown, and if you’re this close, it won’t make a difference.

              So your argument is that since it’s increasing velocity, the force given from its momentum is increasing, but decreasing that momentum by robbing it of some velocity does not decrease the force.

              Does my summary of your argument sound correct to you?

                  It didn’t. The video of the riot in question that I posted shows that. Which is probably why they haven’t replied to the thread since.

                  But even if it did, a hook is also rotational force, and boxers still roll away from it to avoid or lessen the blow. I think if that was the wrong thing to do, they would have stopped doing it several decades ago.

                  the rest of the comment totally misrepresented what was happening here. the protestor isn’t backing away, they’re moving downwards. the officer isn’t swinging the baton, he’s punching straight downwards with it because he didn’t get a chance to swing.

                  now that you are up to speed, try again.

            By all means do try your “elementary physics” in real life, I beg you. Film it too if possible.

              I don’t need to? boxing and MMA have existed for decades now, it’s been recorded likely thousands of times by now. see my reply to the other guy.

              it’s called impulse-momentum theorem. if you apply enough force to an object in motion over a long enough period of time, you reduce its momentum.

              if you had fast enough reflexes, you could stop a punch to the head without it harming you by moving away from it at nearly the speed it was approaching you. while no human can reliably do that, moving away from any blow reduces the force of that blow by an amount that is measurable.

              in boxing, they call it rolling with the punches. even if you are hit, rolling with a punch lessens the blow of that punch when it connects.

                That isn’t how attacking with batons work. They come from the side because it’s rotational, not linear. If they’re stabbing at you, sure. But they aren’t.

              it’s 2025, and people on Lemmy are asking why stealing the velocity of an object over time reduces its momentum.

              I’m not going to waste my time explaining this to you. if you really are interested in impulse-momentum theorem, watch a video on how seatbelts, air bags, and crumple zones protect you when you get into a car accident.

                I’m routinely surprised by just how confidentiality wrong a lot of Lemmy users are about pretty basic things. Like at least on reddit, those people would get corrected and buried in most sane boards at least, but here there seems to be an abundance of those who just want to be incorrect about dumb shit

                Wow, so many fancy words… how about angular momentum?
                And including the length of the baton and the radius of the trajectory?
                Is the impact stronger if hit near the base of the baton or its extremity?

                Please, get someone to hit you with one under these scenarios, you know, for science.

                  it’s OK to just admit you don’t know and were wrong. it doesn’t make you less of a person. this comment didn’t even argue anything, you’re just dragging the conversation out because you don’t have a good response, but want to get the last word in.

              So if an object in motion with the force of 1 newton hits an object at rest that’s 1 newton of force applied, yes? Now if the object instead hits an object also in motion with 0.5 newton, will the first object hit it with 1 or 0.5 newton?

                  Yeah and that was not the answer you got but an example. Do you follow why the baton would not hit as hard if you moved away? 😄
