Impulse Momentum Theorem + Egg Drop??

I have to explain how the impulse momentum theorem relates to my egg drop. My egg was padded with a styrofoam cup and tissues and a plastic bag parachute. Honestly, I don't understand the impulse momentum theorem and I am in need of help!

I have fall times, the drop distance, final velocity, avg acceleration, mass, impulse, and max KE if that helps.

All I know is that impulse is directly related to the change in momentum.

Re: Impulse Momentum Theorem + Egg Drop??

This is a guess:
Your egg drop project is the mass, and it is falling with a changing velocity. For something to have momentum it has to have mass and velocity. Next, the momentum of your project is falling and when it collides with the ground it is stopped by a force over an amount of time. Force over an amount of time is an impulse.

Hopefully that helps...?

I understand that stuff, but I don't get this: my teacher said if you increase time, force slows down. If you increase force time usually slows down...how does that apply here?? I feel like I'm just sounding like an idiot haha

Oh, say you have a give momentum. To change it you can increase the time and make the force smaller. Or make the force larger and make the time smaller.

Example: 100 Newtons X 1 Second = 100 Newtons per second
5 Newtons X 20 Seconds = 100 Newtons per second

See same Impulse, but different amounts
