The Impulse of a Force - A Level Physics

This video introduces and explains the impulse of a force for A Level Physics.

When a force acts for a time it changes the momentum of an object. This is useful if you need to explain how an airbag in a car reduces the force on a person, or even how to get a straw through a potato!

The impulse of a force is defined as the product of a force and the time for which it acts.

Thanks for watching,

Lewis

Excellent video! Wasted one egg = thousands of people getting the concept more

[TheSmurfyman]

You helped me get my A in AS, looking forward to this years videos!

[AkornFPV]

Wow this was an eggcellent demonstration Lewis!

[sabrinaislam]

I love your videos so much, and I just received my AS results and got an A. I think you have a HUGE contribution to my grades. Thank you!

[thomasconway]

that right there sir.. was a cracking demonstration😆 bout to pass my a level mocks now so ty

[nosir]

Amazing video. The revision guide didn't really help me after 20 mins, but I understood it instantly after watching your video once!

Also, +points for the egg

[QuaBaller]

Could you not integrate instead to find the area of the graph at 2:00. In questions like these are we given an equation? Or is that too advanced

[waleedsohail]

this explains how I was able to dodge eggs while running even when they hit me while I was being egged by friends.

R.I.P egg great video relly helped me a lot thanks

[markhenry]

do you mind making a video on the concept of momentum and impulse, im still having a tough time grasping it :/

[mikey]

Is this like a concept of how in D.C comics, the flash can vibrate his molecules so fast to the point of atomic level, that he can go through solids?

[thgamingshorts]

i was not eggspecting you to throw that egg
