Physics experiments

Señor Juárez

11pm the night before the exam? Not a clue what experiments to concentrate on?

Word on the street is:

1) Snell's Law
2) Speed of Sound
3) Simple Pendulum
4) Specific Latent Heat (Vaporisation of water/fusion of ice)

Not so sure on the second two, but there you go anyway.

JackKelly

will do.

Two more I think are a pretty good bet: f prop. a/momentum; and apparent depth/real depth.

f prop wots that?

you talking bout newtons second law?

Crap.

*runs away screaming* :eek:

myeh

and apparent depth/real depth.

*runs away screaming again*

I've got a baaaaaaaaad feeling about this exam I studied for it alot aswell...

Yeah

Dont worry bout physics. Probably a bit late for this but tis for any nighthawks out there. I say, if you're really screwed and don't know what to do just study

1. Experiments (do the likely ones, i'll list em below)
2. Mechanics (easy)
3. Electricity (always 2 qsts)
4. Option (particle in my case - easy 13pages)

Then you even have a choice with that. 5 is always general, simple if you ask me. 2 elec questions, 1 option qst and maybe q12 or the q on mechanics. thats ur 5 q's from section B

3 out of 4 exps from A. couldnt be easier. learn the graphs and formulas from the popular 10exps and youll be sorted:

1.speed of sound
2. F=ma
3. snells law
4. Heat capacity of water
5. calibration curve
6. pendulum

theyre my predictions. more people say
7. ohms law
8. measure velocity and acceleration
9. focal length

we'll see whose right tomorrow won't we... Anyway good luck to everyone. Don't stress out too much though.

Damned chemistry still to go after this **** exam and the engineering. Oh the pain of it all :mad:

ahh I think I had two out of there. I had forgotten to look at the electrical experiments, but I had the characteristic curves covered myself, even though I didnt answer on them. The conservation of momentum was simplistic.

The speed of sound experiment came in useful for me as well, for the experiment to show that sound is also in the form of waves (can be interfered, therefore must be waves)

Or just set up 2 loudspeakers emitting sound of same frequency. Walk in front of them. You will experience increase in loudness and decrease due to con and destructive intereference. Sound is a wave motion.
