Are you tired of Newton’s laws of motion yet? Well, lucky you, this is the last one. And it’s the most misunderstood as well! People love making inappropriate metaphors with scientific principles, unfortunately. Watch this to make sure you don’t do the same!

If only I had seen this video when I first started learning about Newton's 3rd Law of Motion, it wouldn't have taken me 8 months to get comfortable with it.
By the way, I've heard a(n) (unsubstantiated) story that Newton had trouble with his 3rd Law, as well. Does anyone know if this was true?
Genious
hello appreciate the video. But I have one thing to clarify. The example you mentioned with the chair has a wrong part I guess. The third law states that every action force has an equal and opposite reaction force, BUT with the same TYPE. So the real reaction force to the gravitational force acting on the guy sitting on the chair is the gravitational force of the guy himself not the NORMAL force of the chair. Since the NORMAL force is not the same type of the GRAVITAIONAL Force. thanks for reading this and please correct me if I am wrong.
There is another force on the nail by the wood called Fwood. Fhammer > Fwood forces the nail into the wood.
Farm is really confusing. It should be part of Fhammer and should not be added.
You are so boring
haha where did the subtitles in Croatian and Serbian come from? I'm quite surprised
Absolutely amazing! Very well done! Thank you!
Thank you professor dave!
Sir action reaction forces should be same type of nature or not
How can immobile bowling pins exert a force equal to the force of a ball propelled toward the pins. Only the ball is in motion. I don't get it. If their forces of motion were equal, like two bowling balls travelling at the same speed toward each other, then you could say their forces are equal. If one of the balls cracks, then you might have to say that one ball exerted more force than the other. Thats in my world though. I guess Im wrong.
What is the opposite reaction in the hammer and nail example.
Done.
If understanding a microscope means an object is something you cannot always see… than isn’t a force a force? Wouldn’t all aspects of knowledge be quantified? You answered your own question.
Light can break Newton's third law:
Wimmer, M., Regensburger, A., Bersch, C. et al. Optical diametric drive acceleration through action–reaction symmetry breaking. Nature Phys 9, 780–784 (2013). DOI: 10.1038/NPHYS2777
Okay this actually explains a lot but I'm still a bit confused. There are people who said that things move because there are other forces at play. Like when you push a box for example, it shouldn't move but there are other forces or something like that (I don't really understand their explanation). Is this explanation is how the universe actually works or is it to make it easier to understand?
Fantastic explanation of this theory. Thanks 🙂
What's the equal and opposite force of your hand in the hammer example?
Prof Dave please correct your mistake on the normal force and weight being an action reaction pair. A lot of students are watching your videos which are very good so a correction would help them.
i'll probs have to watch a bunch of videos to get this. perhaps my subconscious will work on it, too
So if telekinesis ever existed would it defy the Third law?
Oh my days thank you soooooooo much
Me: Punched car's door
Car: Door punch me back
Thank you so much po, this really help me!!!♥️💕
Would the nail not experience an upward force from the wood when it is being hammered? Can someone please explain this to me.
Because of u now i love science 🧪
