Umm well we can, water can be made to flow up hill on a slope.
http://www.livescience.com/environment/060329_water_uphill.html No, it can't. The water is propelled by steam. It's not flowing, it's boiling. And steam makes a frictionless cushion so it should be shooting downhill. There was also another URL which you have conveniently snipped from your reply. "Bill" wrote: And water vapor goes up to make clouds all without the help of scientists or steam. Nice backpedal. You really urped on that one "Bill." Gravity does not exist at the LaGrangian point. Yes it does. Gravity always exists. At a LaGrange point, the gravity of one mass is cancelled by the mass of another. So gravity has no effect on free bodies at a LaGrange point, but gravity still exists. Oil droplets could go up or down under the control of Milliken. Wrong again. Oil droplets could appear to go up or down under his telekinetic control. "Seems" is not the same as "is" no matter how much it appears to be. If one accelerates toward the earth at the correct rate the gravitational field disappears. Nope. It is cancelled out by the acceleration (the "correct rate" happens to be 32 ft/sec/sec, or about 1 g.... how difficult is it to figure this out?) but gravity never "disappears." Photons do not change speed due to acceleration in the earth's gravitational field. They change colour. An energy effect nontheless. Does a net change in energy always cause a change in velocity and only a change in velocity? There are other forms of energy. A clock runs at two different rates for two observers travelling at different speeds. No they don't. They run at different rates relative to the observers. In other words, "Bill" you flunked the physics test and you don't know as much as you think you do. In spite of all these wonders there still ain't no such thing as a free lunch. Got that one right.... the 1/2 pt extra credit doesn't save your grade though. DSK |
