Paperclip Investigation

Plan

====

I want to find out how affecting the amount of paper clips (weight)

will affect how fast it takes a spinner to fall to the ground.

To make the investigation a fair test I am keeping these things the

same:

· The spinner size

· The height at which it is dropped from

· The size of the paperclips

The only thing I will change is the amount of paperclips added each

time.

For the experiment I will drop a paper spinner from distance of 2

metres and measure the time it takes to fall to the ground each time

adding a paper clip and recording the different times. From this I

will be able to see if weight affects the speed at which things fall

due to the influence of gravity.

Prediction

I predict that the more paper clips added the faster the paper clip

will fall. I say this because I know that the more weight added the

more force will be added too.

Analysis

The graph shows a significant pattern. It shows that as more weight is

added the time it takes to fall decreases. I also saw that the line

starts off at a steep angle and curves as the paper clips are added.

The factors I changed in this experiment was the amount of paper clips
