It would seem that the longer the wing is, the more it slows the helicopter down, except when the hinge cannot support the wing. From this we can deduce that the air exerts a force on the wings: As paper especially normal A4 is a very flexible substance, the wings bend up. I will use the same helicopter throughout the experiment. The smallest of touches could deform the paper, and subsequently alter the wings.
The area of the wing will be kept constant at cm2, and the height will change at intervals of 10 cm. Safety Notes Flying objects are always a concern around children. So, the wing bends up a lot when dropped, and subsequently drops much faster. When things fly on earth, drag is caused by air in our atmosphere pushing against the object. Each paperclip that I will use weighs 1. Because the wings are deflecting the air, they are therefore exerting a force on the air. Again, the height will be constant at 6m.
As paper especially normal A4 is a very flexible substance, the wings bend up. Because there are forces acting on different sides of the helicopter, and in opposite directions, the helicopter will spin anti-clockwise in this diagram.
The top half of the piece of paper is cut [ ]. As one of the variables that I will be measuring is the height from which the helicopter is dropped, I will set up a tape measure, and drop the helicopter from intervals of 1 meter.
The top half of the piece of paper is cut down the middle, creating the two wings, and then the rest of the piece of paper is folded up to make the body of the helicopter.
The basic explanation for this is related to the position of the wings during its flight.
Although my results have been quite consistent and predictable, I think that there has been one weakness consistent throughout the coursework. Below is a picture of one of the helicopters used.
If the terminal velocity is reached almost immediately, then the graph of time to cursework against height will be a straight line and the graph of velocity against time taken will be a horizontal straight line. The readings will be taken with a constant height of 6m, and mass of 2.
Physkcs will obviously be a horizontal component to the forces on the wings.
For varying the mass of the helicopter I intend to attach paperclips to the body of the helicopter. This is how the rotor blades on a helicopter work.

This is because it takes energy to give the object its momentum. Note that in outer space, there is no air and therefore no drag! When we take air resistance into account, is the acceleration for all helicopter the same regardless of the mass? This means that the horizontal component is far greater, making it spin quicker. When the wing is very high and thin, there is very little strength in the hinge on the wing. However, the helicopter revolved too fast to get any accurate measurements.
Physics Coursework Paper Helicopter
Menu Managing company ethics and social responsibility essay What to include in appendix thesis An analysis of the new stage of human life span in the 21st century. Even when the area of the wing is kept constant, I still think that changing the shape of the wing can alter the air resistance. I intend to do this by attaching paperclips to the body of the helicopter.
When the angle is 20 degrees, there is a very small cross-sectional area, so there is less air resistance. I will keep the height of 6m constant throughout the experiment, and use the same helicopter throughout the experiment. From this helkcopter can deduce that the air exerts a force on the wings: Suggest a hypothesis to explain why a paper helicopter falls at a different average speed when it carries a different weight.
The angle of the wing will be my variable. The amount of air resistance that there is on the helicopter is obviously highly dependent on the size of the wings. Because the wings are deflecting the air, they are therefore exerting a force on the air. When things fly on earth, drag is caused by air in our atmosphere pushing against the object.
The Physics of Paper Helicopters
Hi there, would you like to get such a paper? While doing the experiment I noticed that the helicopter reached its fastest spinning speed very quickly.
So, when you start to spin a playground ride, for example, it is much harder to spin it to begin with than once spinning, just like pushing a car. The graph belicopter wing aspect ratio against time Graph 7 in appendix shows that there seems to be an optimum ratio between the height and width of the wing. The basic physics of the paper helicopter As Physics coursework paper helicopter helicopter falls through the air, it spins.
