Falling paper cups

As my object I have chosen to use cake tin liners. This is because the shape of their flat base and lifted circumference is easy to drop without it turning when airborne.

Before I start my investigation I am going to clarify the difference between velocity and speed as many people get this wrong.

Velocity is the distance traveled in unit time in a confirmed direction.

Speed is the distance traveled in unit time, without knowing the direction.

In my investigation I am going to drop cake cups from several heights to calculate the constant speed that the cups will travel downwards. This is called the “terminal velocity”. As I do this I will add more cups to the original first cup to find out that if you double the weight it also doubles the speed.

From my own scientific knowledge I know that the weight of the cup(s) are pulling the cups downwards, air resistance (drag) is the force pushing the cup(s) upwards when it is falling.

When the cup(s) first falls there is a force from the weight of the cup(s) but
