Obviosly the producers of Top-gear have no previous education in classical physics. I never saw the episode but, there is no magnet that would offset the potentially huge amount of POTENTIAL ENERGY stored up in the mass x acceleration of the vehicle to offset any magnetic repulsion...

http://www.cnn.com/video/?hpt=hp_t3#/video/us/2012/04/18/dnt-scientist-beats-traffic-ticket.xetv discuss? My speaker is not working so will see what others have to say.

Canadian physics standards may be different then that of US Standards. I am middle aged but wanted to try for the electrician apprentice program offered by the local technical collages. In order to be a apprentice, 11th grade physics and 11th grade math are pre requirements and I will be...

Well, I missed the opportunity to try this. Seems, within the first one two two minutes, you can balance a egg on its end when the Earth is at its solar minimum called the winter solstice..the shortest day of the year. Now, I figure, the Earth's gravitational constant in relation to the...

IF the jack stand was locked to the frame or axle, it would be as safe as tires on the vehicle. After all, isn't a tire like a jack stand? Axle resting on wheels resting on tires? If a center of gravity was REALLY low because of its massive pad footprint, I would think it was just as safe. I...

sloped grade means any surface of road that has a slope to it. Now, if the car is in the air on both ends, all its weight is pressing down on top of the jacks. think of it this way, if the jacks pad was large enough, there is no way for it to slide "think of a tire contact patch as a jack...

I do mobile mechanical work on customers cars. If the car needs under car work, I always ask "Is the car on a slopped grade?". It is very unsafe to jack up a car on a sloped grade and rest it on jack stands with the possibility of the jack stands tipping over if the grade is to slopped. I was...

Everyone, I Always have had some what of a accurate prediction of future events but often, do not follow up on them. Now the magnet idea would not fly as one user had suggested. One idea that WILL happen in the future is cars WILL be in constant communication with each other. Each car...

such a simple question to ask. I can think of three of perhaps a hundred examples that I may not know of. - Quality control of a product - thanks for the info! -Perhaps working for UL laboratories -Working for the crash center for GM -DOD explosives ordinance testing by a civilian...

Thanks for the reply. I wonder if there is a chart that would show what the KV at the plug should be with the compression of the engine? This would also be different with a turbo or a supercharger? I imagine with very high compressions, the spark would jump the gap, but would be very weak if it...

Honestly I do not think automotive techs would know the answer to this question so being said from a physics stand point about the relationship between the high voltage spark on a spark plug and compression in a engine. I have had experiances where there was spark on the plugs but the engine...
