  • This physics video tutorial explains the basic concept of newton's third law of motion. It contains plenty of examples demonstrating newton's 3rd law of motion in action as well as a few practice problems calculating force, mass, and acceleration. Newton's third law states that for every action force, there is an equal but opposite reaction force. So action and reaction forces have the same magnitude but are opposite in direction.

    Man you are so awesome. I really admire your passion in teaching and somewhat envy you :(. I don't know your age or if you're already in college or what, but you sound just like an average senior high school student. So the fact that you've already nearly-mastered all branch of sciences and also math is truly mesmerizing. Not to mention you now teach what you already have known, or you're just really a fast learner who read, study, and teach what you learned. Nonetheless I hope you the best! Keep doing what you're doing 'cause it fuels me to learn more about science (especially Chem). Last 4 years, I have been trying to master every branch of Math up to Calculus now that I'm in the 12th grade. But then I realize that I need to be a jack of all subjects to be the top student in my class. How I wish you also make Biology videos hehe :)

    For starters, thank you for yet another great video. IMHO, I think your channnel is one of the best science and maths channels on TH-cam.
    1. I do have a slight problem with your skater analogy. You do not have to be standing on ice to "feel" (0:42) the reaction force, from throwing the ball. I would possibly have clarified the role of friction, or rather the lack thereof, in this case a bit better.
    2. Regarding the astronaut analogy, you correctly state the assumption that there are no other planets nearby (3:16) so it is just out of interest then to note that, in a normal universe filled with planets and all sorts of other stuff, throwing the ball "down" will NOT move the astronaut "up", it will merely increase the eccentricity of the astronaut's orbit* AND most likely not even in the intended direction. I can envisage a scenario for e.g. where throwing the ball "up" will also move the astronaut "up".
    * ALL objects in space are ALWAYS in a net trajectory influenced by gravity from ALL other objects in space.

    In your example Lucy applies 540 N force on Sarah and Sarah just standing there. Is that correct? so that is how the equation ended up as you have it. What if Sarah wasn't just standing there but also exerted say another 200 force on Lucy at the same time. How would your equation would like then? Thank you.

  • @alchemy1
    @alchemy1 5 ปีที่แล้ว

    So lets say I am just standing and not exerting any force on someone at all and some guy comes and pushes me with a 1000 N force why do I fly 2 feet back. I exerted no force at all. Or you mean the fact that because I was standing there with my mass and then I accelerated 2 feet back shows that I had applied 1000 N force and the combined push back of force on me ( My mass X that acceleration) was what I got back? Is that how it works?

    • @jamesonskalinski6910
      @jamesonskalinski6910 5 ปีที่แล้ว

      You did exert a force. It might not have been on purpose, but if something is Contacting you, you're exerting a force on it. Imagine trying to exert a force if 1000 newton's onto open air. You simply couldn't. You have to have something to push against, and whatever you push against pushes back just as hard. Now in his example, the reaction wouldn't really occur quite like that unless the people were in space. But as long as you have two feet on the ground you can redirect the force that is pushing you to the ground.

    This can't be true. NIST (National Institute of Standards and Technology) have proven that newton's law is incorrect. They stated that WTC 1 & 2 collapsed at speeds just short of free fall due to the smaller, less dense portion of the 17 upper floors took out the bottom stronger and more dense 93 floors in 11 seconds.
    Further they state that wtc7, 47 story's high collapsed at free fall speeds on 6.5 seconds due to office combustion fires on several floors.
    If you take a loom at the collapse of all three buildings, including wtc7 where No plane hit you will see that the law of motion did not exist that day. It was as if newtons law was suspended for that one day. Take a look

    • @jamesonskalinski6910
      @jamesonskalinski6910 5 ปีที่แล้ว +1

      In the case of the ball and the person it's a much easier visualization. But in the case of the rocket or balloon, the gasses still have masses. So think of it as if the balloon is throwing the air, which is a tiny mass and therefore must be moved very quickly, to move itself. Actually a balloons mass is tiny too. Rockets are much more impressive. The mass of fuel on them is not at all tiny. And the speed is amazing. The fire coming out of a rocket engine is about as hard as an eraser.
