Physics/Expert Profile
Expertise
I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.
Experience in the area
I'm a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. I teach physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science.
Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.

Much more than twice, actually, and rail guns are reeeally old-hat. They were invented in 1918, almost a hundred years ago. I mean, most of the real research in them was done in the 80's as part of Reagan's
2012-02-07 Astronomy:
What about astronomy interests you? What kind of equipment do you have? Astronomy projects that will actually impress anyone are very difficult. How much time do you have? Most science fairs in the

Of course it takes more force to accelerate the larger pucks. In the real world, ice is a funny creature. It doesn't obey the nice linear drag function that you're taught in physics that applies to most
2012-02-06 hockey pucks:
Assuming they were pushed at the same velocity, which you didn't say, the mass terms in the conservation of energy equation will cancel. They'll go the same distance.
2012-02-06 Balancing of static motorcycle:
Of course it depends on the angle and the location of the center of mas of the motorcycle. You simply balance the torque of your support (which would seem to be a kick stand, given the distance you mentioned)
