GCSE Physics - Momentum Part 2 of 2 - Changes in Momentum #60

In this video we cover:
- How to calculate an object's momentum
- The concept that applying a force to an object changes its momentum
- How to calculate a change in momentum using the equation 'F=(mv-mu)/t'
- The idea that reducing the rate of momentum change results in a smaller force being applied to an object, and how this is applied in vehicle safety measures

I literally cannot thank you enough youre the only chance i have at passing my igcses THANK YOU FROM THE BOTTOM OF MY HEART

[ek]

Since this is the last Cognito video I'll ever watch (I have my last two GCSEs tomorrow, physics and geography) I just wanted to say thank you for making such great videos. You've been so great since I made a note of the channel of a video my Year 9 chemistry teacher showed us over two years ago and I honestly don't think I'd be able to cram as well as I have been without these videos to watch. You explain everything so well without over-complicating it and I love the animations, especially the nerve cells in the biology videos. Thank you so much

for yall
00:05 Forces can change an object's momentum
00:52 Force required for change in momentum
01:37 Calculating force using change in momentum and time
02:20 Calculating force required to accelerate an object using momentum equation.
03:12 Calculation of final momentum and force using equation
04:05 A sudden decrease in momentum can cause severe injuries
04:48 Safety features in car design
05:30 Objects lose momentum more slowly because they're compressible.

This is an awesome seatbelt to pass physics exams, without getting crashed.

hellooo cognito!!
honestly just want to thank you guys yet AGAIN for being such a help in my gcse path right now.
been watching (and commenting) since year 9 mock exams and this time im revising for my actual gcses!! aiming for all 9s in my actual exams fingers crossed!!
have to thank both of you for putting all of this together you’ve helped me so much, im forever grateful!!

[randomtimes]

Thank you, this is literally the only chanel where I actually liked, shared and subscribed

This guy! still replying to comments on a 3 year old video wishing them luck, What a legend!

[supertrinigamer]

No idea how to thank you other than saying thanks, because this has saved me. I've been doing online lessons for a while but the explanations I find sometimes are absolutely horrid, but not this. I actually was able to sit through it.

[sammak]

got my paper 1 tmrw, aiming for a 9. Ive been using your videos to revise all my sciences, they are amazing thanks so much

[DreamingSheep.]

This is one of the easiest and most simple tutorials I’ve watched, really helped me with my homework, thanks a lot 😁

[saiamoghasenthilkumar]

Thank you so much ! I have my physics exam coming up on Monday this really helped me.
I Subscribed !

[jpvxjnd]

U don't even know how many people your helping with these videos. Thank you so much

[fbr]

This is indeed a life saver i cant thank youuu your effort is amazing and plus i just subscribed

[Q_TheFun]

will I get a high grade in gcse if these videos is the only thing I revise from?

[leeknow]

seriously thank you so much for making these videos i literally love you bro.

[iffatduaashakil]

This is so good I literally got 98 percent on sessionals of physics

[OmegaShark_]

man your a life saver thanks alot i cant show u how much i appreciate u

[motasemsalem]

The best physics channel ever you helped me alot🤍

[NaBiiii]

Thank you! You helped me a lot btw I just subscribed!!

[ferashasan]

You're videos are amazing!!!! Thank you so much for helping me understand these topics :)
