Question 17
Work in groups to investigate how the shape of an object affects the time it takes to fall.
Design an experiment to test your hypothesis using these guidelines.
- Identify the dependent, independent and control variables.
- Decide which shapes to test.
- Determine the height from which the objects will be dropped.
- Plan how many trials will be conducted for each shape to ensure reliable results.
- Decide how you will collect and record data.
- List the safety precautions you should take.
- Carry out the experiment and record your results.
- Repeat the measurements until the results are similar.
