flew a pitiful average of 36 inches. See graph 1‚ page 5. It wasn’t as terrible as others I suppose‚ but I had yet to witness a catapult that flew a shorter distance then ours. The experiment didn’t necessarily have a set up. We had a measuring tape‚ and it was required that we shoot our marshmallows from the ground. It resulted in a bit of difficulty at first as we watched our marshmallows skid across the tile‚ whilst we argued over which square it landed on. We usually picked the farthest one

of Magnets Objects having magnetic field is called as magnets. Normally magnets are of two types- Permanent magnets and Electro magnets. Permanent magnets are those magnets which occur in nature and do not depend upon external source for their magnetic field. On the other hand electromagnets are those magnets which use electric current to generate magnetic field. Classification of Magnets There are different types of magnets with different physical and magnetic properties and strength. These

THE GREATEST INVENTIONS What is the greatest invention of all time? . There are many different possible world’s greatest inventions because they have all helped out humankind in some way‚ some more than others. I think that the greatest invention of all time is Harnessed Electricity. Some may argue that this was not an invention it was a discovery but although electricity itself was a discovery there was still the invention of had to use it and what it could be used for. I think that electricity

(1) an electric current or a charging electric field produces a magnetic field or (2) a charging magnetic field produces an electric field. In 1820‚ the Danish scientist Hans Oersted discovered that a conductor carrying an electric current is surrounded by a magnetic field. When he brought a magnetized needle near a wire in which an electric current was flowing‚ the needle moved. Because a magnetized needle is moved by magnetic forces‚ the experiment proved that an electric current produces magnetism

Hendershot Fuel Less Generator 2 Hendershot Fuel Less Generator What is a fuel less generator? All over the world‚ people live with the idea that it’s necessary to burn fuel in order to produce power that we can use. We have been persuaded that we have to buy coal‚ coke‚ timber‚ kerosene‚ gasoline‚ diesel‚ propane etc to burn‚ so that we can obtain our precious energy. And yes‚ it is perfectly true that burning these materials will indeed result in energy. And yes‚ we need it

Project Abstract The objective: I continued in this project because I felt that I had more to learn in this subject and that my project had not yet been able to reach to its full potential. In my research‚ I discovered the many laws that when using magnetic acceleration you are altering the forces that are attracting one magnet to an object. The reversal is used in switching plates and gears in most machines because the heavy equipment can only be moved using a powerful enough shift of energy to move
