The Slowest fall / simple aerodynamics

In summary, the problem is to create a model using materials such as paper, blotting paper, foil, and tights that will fall along a 3 metre long runner with the longest possible time. The proposed solutions include a paper towel parachute with holes for air circulation and a propeller model with a tube and three blades. The goal is to use air resistance to maximize the time the model falls along the runner.

Homework Statement



The problem is to construct a model out of ordinary materials such as paper, blotting paper, foil, tights and so on, that is supposed to fall along about 3 metre long runner with as longest time as possible. (with the inspirations like maple seed)

The Attempt at a Solution



I was thinking about a paper towel parachute with holes in it that would keep the air circulation not to swing around... Or the propeller model with tube (has to have a hole for attaching it to the runner) and 3 blades like in helicopter...

What is the best way to use air resistance in this case?
I'm sorry for such dumb questions =_=,
thank you

"to fall along about 3 metre long runner with as longest time as possible."

Please elaborate...

There is a line attached to a celling and there should be a hole in the model so that it goes along a restricted space (to measure time equally)
 

Related to The Slowest fall / simple aerodynamics

1. What is the slowest possible fall rate for an object?

The slowest possible fall rate for an object is when it reaches its terminal velocity. This is the point where the force of air resistance is equal to the force of gravity acting on the object, resulting in a constant velocity.

2. How does air resistance affect the speed of a falling object?

Air resistance, also known as drag, is the force that opposes the motion of a falling object. As the object falls, it moves through the air and the air particles collide with the object, slowing it down. The larger the surface area of the object, the greater the air resistance and the slower the fall rate.

3. Does the mass of an object affect its fall rate?

Yes, the mass of an object does affect its fall rate. The heavier the object, the greater the force of gravity acting on it and the faster it will fall. However, the mass also affects the amount of air resistance, so a heavier object may reach its terminal velocity at a faster rate than a lighter object.

4. How does altitude affect the fall rate of an object?

The altitude, or height above the ground, does not significantly affect the fall rate of an object. However, at higher altitudes, the air is less dense and therefore provides less resistance to the falling object. This can result in a slightly faster fall rate compared to a lower altitude.

5. Can the shape of an object affect its fall rate?

Yes, the shape of an object can greatly affect its fall rate. Objects with a streamlined shape, such as a feather, will experience less air resistance and therefore fall slower than objects with a larger surface area, such as a flat sheet of paper. This is why skydivers use specialized suits to increase their surface area and slow down their fall rate for a safer landing.
