Weight at Equator is less

Weight at Equator is less

The reason we weigh less on the equator than the North or South Pole is because the force of gravity and other forces change as you approach the poles. The Equator is not a weight loss program, the force changes back when you return to your original latitude. The forces that make us feel that way are, The Moon's Gravity, Earth's Gravity and the Sun's Gravity. 

The Earth has a bulge at the Equator  which is created by the Planets rotation. This is known an Centrifugal Force. All this a Newtons law of motion which is felt.

How Electric Current is formed?

How Electric Current is formed? Have you ever wondered how Electric Current is formed? Generally, the flow from one point to another through a medium is called a current. When an electric charge moves from one point to another inside a conductor or a semiconductor, it is actually conducting electric current. Electric charge carriers are micro particles that conduct the electricity. They can be protons, electrons, holes or ions depending on their availability in the conducting material. Normally electrons and holes are responsible for conducting electricity. This process occurs when a Voltage or a Potential Difference is applied at the two ends of a conductor or a semiconductor. Thus Electric Current is formed when a Voltage of Potential Difference is applied at the two ends of a conductor or semiconductor, i.e. when a closed circuit is formed.

Evolution of Aircrafts

Since that fateful day in December of 1903, airplane design has changed dramatically. The Wright Brothers built a biplane with two propellers that were chain-driven by a gasoline motor. Our dependence on air travel over the years has forced airplane design to catch up with the times. On December 17, 1903, Wilbur and Orville Wright made four brief flights at Kitty Hawk with their first powered aircraft. The Wright brothers had invented the first successful airplane. The Wrights used this stopwatch to time the Kitty Hawk flights. Aircrafts have evolved so much from the initial days. From 2 seater to the latest air bus type, they have come a long way. The history of aviation extends for more than two thousand years, from the earliest forms of aviation such as kites and attempts at tower jumping to supersonic and hyper-sonic flight by powered, heavier-than-air jets. Kite flying in China dates back to several hundred years BC and slowly spread around the world. Sir George Cayley...
