    Practical Project Help : The Resonance of different pieces of metal.

    that sounds like a very good direction to go in. I've as yet had no luck finding a good resource for what you mentioned via google, hopefully there will be something in my school library. I am assuming these equations will be mighty complicated though? They'll have to take into account the...

    Practical Project Help : The Resonance of different pieces of metal.

    Thanks for all this info so far it is very usefull. hehe, yes, sorry, i am aware of how resonence is an important consideration in the design of aircraft, bridges, cars, etc, i was just being slightly sarcastic in regards to my project because i was unclear what i would be showing if i gather...

    Practical Project Help : The Resonance of different pieces of metal.

    Hello forum. I'm in abit of a mess. My high school physics class is in the process or doing individual investigations into an aspect of physics we are slightly familar with. I had planned out an experiment to do with sound, but last minute i was told another person was doing something...

    Waves Investigation [Using water]

    hi in my physics class right now we've been told we're going to be to doing an experiment where we put a variable amount of water into a tray, hold one side up, and drop it from a variable height, thus, when it hits the table, the water will move and waves will ocsillate back and fourth...

    Velocity Time graph question [i'm not getting anywhere]

    thanks very muchfor that tip, i worked it out now, very simple in the end :( but the next part says "the distance from A to D is 675m, find a and t" [from earlier. the answers are a=1/8 and t=20. i just can't get to these answers, I've tried writing what i know [s, u, v] and trying to...

    Velocity Time graph question [i'm not getting anywhere]

    "As a car passes point A on a straight road, it's speed is 10m/s, the car moves with constant acceleration, a m/s/s, along the road for T seconds until it reaches point B, where it's speed is Vm/s. The car travels at this speed for a further 10 seconds, when it reaches the point C. From C it...
