Unfortunately, due to the lack of public access to private prison contracts, most of the details are unknown. Shortly before her death, the woman reported that she had been raped and assaulted by male inmates who were housed in the same cell block.
Hire Writer This supplementary weight would cause a greater resultant force in the favour of gravity, which would cause a greater acceleration. This is because the weight is great than the drag force, causing there to be an unbalanced force. Chosen Variable I have decided choosing the total surface area of the wingspan in my investigation and the reasoning behind this decision is that I believe this variable from my preliminary work would be much better to collect results from for my analysis.
When executing my preliminary tests prior to this investigation, I noticed that when dropping my helicopter with an altered mass, the vertical acceleration time did not seem to have considerable differences between the starting and finishing points as it did for the wingspan.
Therefore, this would make the investigation very difficult to accomplish since there is not much evidence to examine.
So I have come to the decision of changing the wingspan, as I think it will provide a more reliable set of results, and will be able to explain more clearly in scientific reasoning for the increase in speed. My plan is to be able to show that my hypothesis is correct but in order to ensure this I must be able to relate the information to the Speed formula to calculate the speed at which the helicopter gradually falls from the certain height.
Overall, I believe the graph will show a negative correlation for both wingspan to time taken to fall and the Speed in relation to surface are of the wings. Therefore, as the wingspan decreases, the amount of air molecules contained inside the cylinder of air would be decreased proportionally to the wingspan.
Furthermore, this would conclude in less air resistance against the force of gravity that forces the paper helicopter to fall because of the reduction of the wingspan, less air resistance would be needed to restrain the overall vertical acceleration.
Although, as the helicopter gradually gains speed, the air resistances would increase likewise, until it becomes so great that it pushes against forces of Gravity, which ultimately forces the helicopter to vertically accelerate downwards.
Nevertheless, eventually the resistance force will become equal to the opposing force, which in this case is Gravity, thus resulting the helicopter in not accelerating anymore since the forces are balanced.
Therefore, it has met its Terminal Velocity maximum speed. This would mean that without gravity applying forces to push the helicopter downwards, it would still eventually land, because of its mass and because of this I would be made to believe that this may another reason for the acceleration of my helicopter.
He also discovered that in most changes of Velocity, more than one force is acting on the accelerated object, such concurrent forces produce a signal net force. If the force pushing down on the helicopter is greater than the upwards draft, there will be a net force in the downward direction, therefore the helicopter will accelerate in that direction.

Fidget Spinners are supposed to help kids with ADHD stay focused. But one teacher and working mom says they're doing just the opposite. Throughout the course of the following investigation, I will be exploring a variety of methods to discover how a changed variable affects the speed in which a controlled type of paper (printer paper), formed into a model helicopter will descend from a specified height.
