I am trying to test how long it takes for the paper helicopter to drop to the floor using this equipment:

1000mm ruler – To make the experiment accurate.

Clamps – To hold the ruler.

Stopwatch – So the experiment is precise.

Paper Helicopter – the paper helicopter is used for testing how long it takes to get to the floor.

A Stand – This is to hold the clamps.

I will do this by getting the stand then putting clamps on it then attaching the ruler then get the helicopter dropping it while timing it with a stop watch.
