What is effect of the weight of the helicopter on the terminal speed?

When an object falls in the air, the air resistance opposing its motion increases as its speed rises, so reducing its acceleration. Eventually air resistance acting upwards equals the weight of the object acting downwards. The resultant force on the object is then zero since the two opposing forces balance. The object falls at a constant velocity, called its terminal velocity, whose value depends on the size, shape and weight of the object.
This is just like Newton's laws, an object will accelerate if the forces acting upon it are unbalanced; and further, the amount of acceleration is directly proportional to the amount of net force (unbalanced force) acting upon it. Falling objects initially accelerate (gain speed) because there is no force big enough to balance the downward force of gravity. Yet as an object gains speed, it encounters an increasing amount of upward air resistance force. In fact, objects will continue to accelerate (gain speed).
Or summat like that...

How does the weight of a car affect the speed?
Weight wouldn't effect speed but it would effect how quick it would get up to speed.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
Will changing the weight of a parachute effect on the speed?
yes, it can
Which is the independent variable in an experiment investigate the effect of weight on the speed of vehicles?
The Weight Change.
Which is the independent variable in an experiment investigating the effect of weight on the speed of vehicles?
The Weight Change.
Why a helicopter falling during auto-rotation could reach a terminal speed without the pilot changing any controls?
The helicopter begins to fall because gravity is pulling its weight. As the helicopter accelerates, the air passing past the helicopter creates drag, as the helicopter continues to accelerate the drag Increases until the drag becomes equal to the weight, stopping it from accelerating. Even if the helicopter did not auto rotate it would still reach a terminal speed, however the terminal speed for the non auto rotating helicopter would be a lot higher and the helicopter would take longer to reach this speed.
Why can a helicopter reach a terminal speed whilst falling during autorotation?

How much does an army helicopter weigh?
Not all army helicopters have the same weight. The Sikorsky UH-60 Blackhawk helicopter weighs 13,648 pounds when empty. This helicopter has a maximum speed of 173 miles per hour.

Because Mr moffat likes to suck eggs

What is the effect of the weight of the wheel of the bicycle to its speed?
It really does not have an effect on the maximum speed, but due to inertia, it does inhibit [slow down] changes [acceleration or deceleration] in speed.
How does the speed of the bike affect its weight?
The speed of the bike has no effect on its weight. Weight = mass in kg x acceleration due to gravity, 9.8m/s2 on the earth.
How does the wingspan of a falling helicopter effect the speed?
It wouldn't, the propellers are designed to propel the helicopter off of the ground, thus the word propeller, not to make the helicopter glide. The wings are too thin to hold up a helicopter and that is why they spin to gain ground as well as using kinetic energy to lift up. The propellers would eventually bend or snap if the helicopter would be to fall, the speed of the wind would break or damage the propellers.
