Exercise 2: Gravity and air resistance
Aim:
This experiment is to verify gravity and air resistance.
Note: After reading through these instructions, you will need to think carefully about what are you trying to determine or prove? You will need to write a specific aim in your report and use the proper report format.
Materials:
For this experiment you will need:
- 3 pieces of A4 paper
- Pen or pencil
Procedure:
There are 5 parts to this practical exercise. Step through the parts on each of the slides below and record your results
Part A: Sheet vs. Sheet
Part B: Sheet vs. Ball
Part C: Sheet Throw
Part D: Ball Throw
Part E: Ball vs. Pencil/Pen
Report:
Write up the results in a proper report format. Make sure you answer the following questions:
- 1) Why did it take longer for the sheet of paper to hit the ground compared to the ball?
- 2) Why was it hard to hit your target with the sheet of paper?
- 3) Did you expect the pencil to hit the ground before the paper ball? Were you correct?
- 4) What assumptions about gravity can you make after completing this practical?
