Impulse Momentum Theorem Physics Problems - Average Force & Contact Time

This physics video tutorial provides a basic introduction into the impulse momentum theorem. This theorem states that impulse is equal to the change in the momentum of an object. Impulse is force multiplied by time and momentum is mass times velocity. This video explains how to calculate the impulse exerted on an object, the change in momentum, final speed, and average force exerted as well given the contact time of the two objects.

Your English speaking style is very understandable. Thank you for that. Greeting from Turkey..

[schalksmith]

Im writing physics tomorrow, you saved me man. Thanks, greetings from South Africa.

[rye-bread]

Thank you. Very helpful for my finals studying.
10/10 would watch again!

[joshpeligrino]

This channel is making distance learning easier 👌

[astranova]

This was so helpful! I really felt like I truly understand the concepts, and you walked through the problems extremely well.

[estherli]

thank you sm for this video! There was an identical question in my worksheet that I couldn't solve but after watching your explanation I got it straight away... now i can move on to conservation of momentum lol

[zi]

I’m not that good at English but I literally can understand every word that you said 🙏🏾👌🏾

[tlili]

love how you explain this better than my physics teacher. also it helps that i can stop the video to have time to understand the problems

[Chivende]

Bless you sir, I'm preparing for my end of semester and I missed this lecture❤❤❤..I get it now

[sirajmunir]

You are amazing I finally understood momentum

[thabomlungu]

Your videos are realy and truly helpful thank you very much for you help it makes studying much easy

[xerxeskarkaria]

Bro you are truly amazing as you make the concepts super clear and hope to see any of your new videos

[your.paolita]

This really REALLY helped me! You’re a saviour thank you very much

[efayyang]

You really save my PHY, so appreciative!!!😍

[deangelo]

Thank you very much. Very helpful right now during school quarantine.

[KingUnity]

Good video, easy to follow and very concise. No extraneous information. I like it.

You know what...you are a genius, you are literally helping me in my studies and you look like a teenager to me (by your voice) what's your age?? If you don't mind ....but man you are just so brilliant 💜💜☺️☺️☺️

[stacy-ann]

Can you please include the SI units when working questions? Would really help to keep me on track, Thanks!

[joedemarkgumapac]

for example 3, the momentum going to left must be -12.5 kg m/s, if the contact time is 0.015 s, should the force be -833.33 N according to the impulse-momentum theory?

I wanna be your student sir. Respect from Bangladesh
