From what I wrote, that is a pretty good inventory. Getting one or two more in there wouldn't be too much of a problem--for instance, you could use a latch to hold back the pinball plunger/spring device that launches the car, then lift it with a lever. Lighting tricks would be easy--maybe you...
I think your first idea was a good one--a Rube Goldberg device doesn't necessarily have to be huge or complicated, and it has the added bonus of allowing you to demonstrate each of those principles separately.
For instance, you could start off with a miniature car on a track that begins a...
It does, shpongle--thanks :) So current does flow when a battery is hooked up, even though this is a sort of "open circuit." Maybe I'm being too rigorous with the wording, but it's frustrating at times when you are given a strict definition, then later referred to that strict definition as...
I'm taking my first Physics course dealing with electricity and magnetism, and I am finding it incredibly difficult. I have a number of questions that are driving me insane, and I hope that some of you will be able to clear things up for me--I would greatly appreciate it.
We are covering...
Is that all of the information that they gave you? It seems like they would have given you some other information, such as the angle between the smooth and rough surface, and especially the friction coefficient for the rough surface (usually denoted by the symbol μ).
As a student, I would have to say that the math teacher does make a difference, but that's not an excuse to make an excuse. I have had a couple of good teachers, and a couple of bad ones. The worst experience was with a teacher that was "faking it."
I realized that he was faking it when I...
