I have an assignment on movie magic in which I have to pick a scene from a movie and analyse the physics (including calculations of physics in movie, description and calculations of correct physics etc.) Problem is, I haven't picked a movie yet :frown: I was going to pick 2 different scenes...

Oh okay I understand :D Thankyou so much for your help!

Yeah I understood the bit about voltage divided by current = resistance. For some reason I'm having trouble with the bit about it being constant. Does it mean that it will not vary? Can you please give me an example of a constant resistance and a non constant resistance?

So to stop the 'back voltage' from happening, would I lower the voltage? Sorry, but what do you mean by Voltage and Current being constant?

Next term for Physics, my teacher has said that he has ordered some black boxes and will be putting a diode, capacitor, resistor and a transistor in each. There is 3 people in my class and he will be making each black box different (he'll put each component between a different terminal)...

Do you mean something along the lines of this ? http://www.absorblearning.com/media/item.action?quick=zy

Hi Everyone :smile: I have to create an experiment for my assignment in Physics. I've chosen to do something about Specific Heat Capacity. A boy in my class is also doing SHC so I wanted to make mine a little different from his. I've just recently joined physics (never done it before)...
