For the balls example, we could also use the equation m1*u1 + m2*u2 = m1*v1 + m2*v2 Dont get confused, U and V are both fore velocities but to differentiate between before collision and after collision, so basically the left hand side is for before collision and right hand side for after collision. If we replace the values we get, 5*8 + 2*0 = 5*6 + 2*v2 because we need v2. 40+0=30+2*v2. Mke v2 subject of formula. v2=(40-30)/2= 5m/s
HELP!!! why does he say the momentum of the 5kg ball is 40 before and after the collision, than works out the momentum is 30 after the collision on the 5kg ball. How can it be both 40 and 30??”
i found your videos just at the exact right time thank you alooot
holy shit. you made that so much easier to understand. thank you!
Thank you very much for your help Sir!
Thank you so bloody much!!!!!!! got a physics mock tomorrow
this man is a beast. HATS OFF SIR
Great explanation!
Ur a great teacher rock on🤗
This is a proper explanations and useful for exams.

XxAsLaNAmmArxX 🙏🏼 thanks!
Lol i have seen u on so many Physics and Chemistry IGCSE videos xD
i dont understand i need help please i have the physics exam on 22😭😭😭😭💔💔💔
@@rubasaleh2637 how ir went g??
Great explanation
Awesome guy
HERO!
Brilliant. Thanks
Very helpful! People with less subscribers teach the best! :)
who else has physics on monday
Thankyou for helping me pass
thank you!
It was very useful to me
This makes so much meaning
God bless youuu
Can you do a video on Waves please for A-level ??
love this video
Thank you hero.
luv your vids
thank u so much
5:16 "and the principle of conservation of momentum"
2:54 is it change in momentum = force x time?
yeah

Find the mass of the rule
thanks you sir

gks see you
i dont get impulse
same here do u have any recommendations ?????
@@hanaashaker987 impulse = Change in momentum
@@hanaashaker987 bro is change in momentum devided by time
Theres no rocket science
UTorrent in the background haha
