Gravitational Potential Energy Near the Surface of Earth - As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth..

As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg) can be assumed to be constan..

About AD1600, William Gilbert, who was a court physician of Queen Elizabeth of England, performed certain experiments using spherical lodestones. When he placed small, pivoted magnetic needles at different positions on this sphere, he found that their behavior was quite similar to t..

Scientists theorize that the earth began as a waterless mass of rock surrounded by a cloud of gas. Radioactive materials in the rock and increasing pressure in the earth's interior gradually produced enough heat to melt the interior of the earth. The heavy materials su..
