Thank you, to this day your video still holds up. This has made it so simple to understand my A level physics

his voice brings me happiness

Hello sir, I just wanted to show my gratitude towards you for the videos, they are extremely concise and well explained. My grades in physics have taken a boost ever since and I always revise these videos before my exams.

really wanna give you hug for this, i have my exams in 8 days and i am hardly prepared... im a pretty avg scoring person. this video really helped me internalize the concepts. thank you so much!

If they collide and bounce off, m1u1 + m2u2 = m1v1 + m2v2 U=initial velocity V=final velocity And if they collide and 'don't' bounce off, final velocity v is the same for both as they are stuck together: m1u1 + m2u2 = (m1 + m2) v

how do yo find momentum when they expect you to use vertical and horizontal component

how can impulse AND momentum both be the area under the graph f=i/t thank you

Because in essence impulse IS momentum. Same units too. Impulse is only the CHANGE in momentum

At 17:02 , if momentum is zero at the start, how is momentum mv at the end if momentum is meant to be conserved?

@MH-wh9ek

2 жыл бұрын

it's TOTAL momentum before the collision equals TOTAL momentum after the collision, he only shows the graph for the stationary object, there would be another moving object that would hit the stationary object before the collision that would balance it out.

At the start you say that momentum is always conserved but then when you talk about the car accident you say that after the accident momentum goes down to zero. Im confused. Can someone please explain

@CAMPer2610

5 жыл бұрын

Cuz momentum is mass x velocity, a moving object would stop after hitting something applying force to the opposite direction of the moving object , that cancels out the velocity , therefore the the momentum which is mass x velocity would be zero since velocity will be = to zero.Hope it help.

17:11

this probably wont get answered but why did you put v^2 in end while deriving the formula through density at 20:33

@MH-wh9ek

so what he got initially was change in mass divided by time which can be written as kgs^-1 which is what he managed to make an equation for at 20:06 but if you look at the initial equation for force for the fluid which he wrote at 17:57 , it is VELOCITY x change in mass over time.

Because you add the two momenta (300+160=460) and divide by 140. 460/140=3.285...=3.29m/s (2dp)

14:33 shouldnt it just be 2mu because v--v adds up to 2u

Change from 'u' to '- u' : You have to subtract one 'u' to get from 'u' to zero, then another 'u' to get from zero to '-u'. So in total it's -2u. Then multiply by the mass to get -2mu.

Or change in velocity is , v - u , so v is final velocity and u is initial velocity, in this case v = -u and u =u , so -u - u = -2u . Thus its -2mu / t. Hope this helps.
