Physics Momentum Video

My Grade 11 physics project on momentum doing this project made me hate PC's or at least windows movie maker.

@slyscafe Luckily you're not a teacher, and yes the matrix part is unneeded yes but still fun and I didn't need to show it in class but just used it for my own amusement.

As for only covering the very basics, thats what it was supposed to do, covering the very basics of momentum was the goal of the project. No I would not under any circumstances have covered angular momentum since that was not part of the curriculum and so not part of the project.

Parts could be more clear though

Just for clarification, I didn't need to show the matrix part, the rest was show in class.

[seriouslyWeird]

terrible explanation

[pithikoulis]

i don't get what impulse has to do with matrix :/

If I were a teacher, I would give this project a C or D. It covers the very basics, and it's entertaining, but it's too long, and the explanations aren't always clear cut.

You never really fully explained WHAT momentum is, and you could have expanded to discuss angular momentum as well. It feels almost as if you were trying to buy time with that Matrix clip. Showing 5 minutes of irrelevant footage and then saying "Impulse time" doesn't explain to me what it is at all.

@JenniferLacey Well gravity causes them to move downwards, not upwards after the bounce. That's why every time they hit an other ball and bounce back away the heigh the get is smaller than the height they had earlier. And that is due to gravity trying to keep them as close as possible to earth, thus slowing down their momentum after every bounce. Friction in this case is not a big factor.

[JenniferLacey]

@pithikoulis why would gravity slow them down? It's what causes them to move. As long as no energy is lost in the system they will continue forever.

@pithikoulis That pole transferred energy to the target objects for a longer period of time also called larger impulse. The larger impulse meant more flight time for those struck with the metal.

Uh, it's sort of fun you'd use a spaceship considering its mass is precisly not constant, it expulses gases and that's how it takes off, so your momentum is just an approximation.

Also two objects remaining unattached after a collision doesn't mean the collision was elastic, you can have a loss in kinetic energy and still have your objects unattached at the end and you get an inelastic collision.

Um maybe this will help somebody. :)

I know how to work out momentum, but WHAT DOES IT DO!?????
