linear motion formula proof,

insane drummer

right, i was looking at s=ut+.5at^2 and i was trying to prove it, using integration, i got it, and let my physics teacher look at it, and he said it wasnt right, because of the same reason i doubted it, the constant of integration. what i wasnt to know is, can this actually be proved using integration? any help would be good

thanks

If you're integrating with respect to t, then you'd set your limits between 0 and t, hence no constant of integration.

That ok? Let me know if you need more detail.

insane drummer

aah yea, that sounds right, thank you alot for that, pitty i never thought of the limits before i showed my teacher., thank you, have a good night,:D

Whoa you're teacher must be very bad! That's pretty shocking.

Teachers are not infallible. They're just human, like the rest of us. I had a science teacher tell my son that copper had the best conductivity. He still got an A in his LC Hons Physics, so it was teaching that she was good at.

Aye, I remember asking my LC physics teacher what antimatter was. She just shrugged her shoulders (it's on the course....).
Still got an A though

In fairness to teachers they prob did college Physics about 25 yrs ago and can't be expected to remember everything. Also I'm doing a Masters atm and I have to think for a few mins sometimes about stuff that's fairly simple but not related to what I'm doing. Something asked out off the blue can really throw ya off no matter how well up on a subject you are.
