first u say m1v1 + m2v2 = m1v1 + m2v2 so basically m1v1 + m2v2 right? then later again you say m1v1 = m2v2. when i refer to another video (WHICH WASS 100% BETTER THAN THIS ONE) he said m1u1 + m2u2 = m1v1 + m2u2 with clear definitions and steps. you have totally confused me. thank you :(
momentum cant be destroyed. it can only be a lot or little. if the object stops the momentum is 0. because there is no velocity. momentum= mass x velocity. so the mass of the object multiplied by the velocity which is 0, in this case, (because its not moving, which means it has no velocity, which means the velocity is 0), is equal to 0. Basically no velocity means no momentum.
If it slows down at all that means some momentum has been transferred - for example if the skaters in the video slow to a stop, it's because of friction, which is their momentum transferring to the particles of the ground.
Let's say you have a 1 kg mass moving to the right at 20 m/s that collides with a stationary 2 kg mass and bounces off to move to the left at 10 m/s with the 2 kg mass moving to the right at 5 m/2. The time of collision is the same for both masses, but the net force is different since the impulse or change in momentum on the 2 kg mass is 10 kg*m/s and the impulse or change in momentum on the 1 kg mass is -30 kg*m/s. How does this figure or how is momentum conserved with the momentum lost by the 1 kg mass not being equal with the momentum gained by the 2 kg mass? How can the net forces be different?
Its interesting how you say the exhaust pushes a rocket forward. So what does the exhaust push off of in the vacuum of space? where there is a pressure of 10 -7 torr (at the ISS)
The exhaust is pushed out of the rocket, and Newton's 3rd law states that the exhaust pushes back on the rocket with he same force. Air/atmosphere is not required for the rocket to be pushed forward.
plz answer this question anyone. As law of momentum is never conserved in case of swinging pendulum but what if we provide a costant force to pendulum that it never stops completely. Is the law hence valid.
Who would be applying a greater force, would it be the man because he has a greater mass or would the women apply a greater force on the man in order for him to accelerate?
Why you said momentum can't be created but momentum can be created by applying force on a bodyyy and by applying force the body will be in motion it gains some moments which will be equal to the applied force
Sہ does it mean when we are talking about conservation of momentum in the collision we actually ignore all the external forces and then there is just one perfect isolated system (universe) and all other are just imaginary?
This is probably the best video available on TH-cam on this topic
fr
was anyone else just watching the people in the background play at the beginning
I was, lol!
I wish I could be your student. Carry on like this. I am always with you.
Great video! I definitely understand the concept better now! Thank you!
This is such an amazing explanation!! Thank you😊
Omg I finally understand about this topic!!
It was a really fantastic video.The elucidation of the topic was really done in a very simple manner which made me crystal clear.Thanks a lot ma'am.

Bane-o🤗
what happens if the object stops? Will the momentum be destroyed? Because momentum is mass in motion with velocity right?
momentum cant be destroyed. it can only be a lot or little. if the object stops the momentum is 0. because there is no velocity. momentum= mass x velocity. so the mass of the object multiplied by the velocity which is 0, in this case, (because its not moving, which means it has no velocity, which means the velocity is 0), is equal to 0.

what a great teacher! well explained...thank you
Glad it was helpful! Thanks for watching!
I love it, make it easier to understand.
Glad to hear that!

Your Welcome
@@Hi-gx1ni Thanks Enrico Pucci
You a real one
very well explained and picturised
Thank you so much 💙

Great video!!!!!!!!!!!!!!!!!!!!
Thanks!!
Why do they have so low subscribers . This is soo good

That's great easy to memorize 😊
Chirag is such a stud!
Wow! Really enjoyed it.
this helped me understand my homework, thanks!
Glad to hear that!

Great video. Thank you!
Hi 😊. Please I have a question ⁉️
Ummm why was chirags mas negative and summer's mass positive??!!😅
Thanks ma, your explanation is superb I love it
Best video ever periodt
Thank you so much
Who would be applying a greater force, would it be the man because he has a greater mass or would the women apply a greater force on the man in order for him to accelerate?
Same force! Newton's 3rd Law!
Awesome video... Plus they must have enjoyed skating
all my questions answered.. thank you !!!
Glad we could help! Thank you for watching
but what about your hand? isn't that which create the momentum?
But what about heat losses when the billards balls hit each other ?
Are these systems only in 1 dimension?
Hence; opposite load sequence, in gravity! Mechanical sine law -- u calculus, bigger then smaller--est!
Machines don't use, till BIN commanded!
In the 2nd ball, why didnt all the momentum get transferred to the blue striped ball? Why did the cue ball retain some of its momentum
Because it was hit at an angle. That’s why.
Love this.
Why you said momentum can't be created but momentum can be created by applying force on a bodyyy and by applying force the body will be in motion it gains some moments which will be equal to the applied force
You dont create the momentum youre transferring your momentum
shouldn't that answer be in negative
very informative video!! thanks
Glad it was helpful!

Yes
Thank you!
commenting before seb gets here
Thank you
Omg that was really awesome❤☺️
Glad you enjoyed it!
you are intelligent :*
❤
If I could like the video a million times, I totally would.
This was pretty nifty.

Dude in the back was having second thoughts every second
its actually kind of funny how much i suck at focusing
Super mam
Woooooow
This was a video
Commenting before seb gets here chapter 2 attack of the sebs
Am also a teacher
Wow only 5 comments
Jet fuel doesn’t melt steel beams
why she kinda
Bro what?
Too complicated. I fell asleep
Sorry but it wasn't helpful
Wait why??
Cool cool.
Awesome video!
Glad you enjoyed it!
