Investigating the falling of paper cake cases

Introduction

I am going to be investigating the rate at which a paper case falls at. We are trying to find what things affect the rate. For example:

* Wind air currents

* Mass/weight of cake cases

* Height from which they drop

* Size of cake cases - surface area

These are what we call input variables.

The output variables are:

* Time of fall

* Forces acting on the case, e.g. gravity, air resistance.

What am I going to change to get my results?

To get different results I have considered, the height at which the case is dropped from. If this is changed then the air resistance and the gravity forces will be unbalanced therefore effecting the time at which it hits the ground. The weight of the case will affect its rate of falling; because its mass is heavier it will fall faster because the gravity is larger than the air resistance.

What am I going to do to ensure my experiment is fair?

To make this a fair test I will weigh my
