AEROPLANE PHYSICS [THIS PAPER WILL ADDRESS THE PHYSICS INVOLVED IN KEEPING AN AEROPLANE LEVEL DURING FLIGHT] For centuries it has been mans dream to fly. Only in the last hundred years or so has this dream actually been realised. We are now able to fly using several different means. For example, there are hot air balloons, which are able to fly, or 'float', due to the lighter than air gas that they contain. Aeroplanes however, …showed first 75 words of 754 total…

This weight is the force that acts vertically towards the centre of the earth, through the centre of gravity of the aeroplane. Weight is one of the four forces acting upon an aeroplane to keep it level whilst in flight. These are; lift, weight, drag and finally, thrust.
