Terminal Velocity
Apparatus: A 100cm ruler
A bun case - (to represent the parachute)
A clamp and stand
A stopwatch
Method:
The clamp and stand was set up at the edge of the table. The distance from the floor to the top of the table was measured and recorded. The 100cm ruler was then secured to the clamp - so the 0cm mark was touching the top of the table. It was important to make sure that both these factors were measured accurately in order to perform a fair test. It was then possible to identify the distance of the fall. Several heights were determined from 0.40m to 1.60m. A bun case was held at the first height and then released (so it could fall to the floor). The time taken for the bun case to reach the floor was recorded using the stopwatch. This was repeated three times for each height, to make it a fair test, allowing room for human error. It was then possible to work out an average for that particular height ((time 1 + time 2 + time 3) ÷ 3). This process was reiterated for each of the nine heights and a table of results was created.
