Experimental Question: What is the effect of mass on the time it takes for a skydiver to reach the ground?
Independent Variable: Mass Dependent Variable: Falling time
Hypothesis: If the mass of a skydiver is increased, then the time it takes for them to reach the ground will increase, because greater mass increases the force of gravity acting on the skydiver which resulted in a greater downward acceleration and a longer time to reach the ground.
Procedure:
1. Gather a group of skydivers who have different masses.
2. Choose a controlled environment for the experiment, such as a skydiving simulator or an indoor wind tunnel.
3. Determine the starting height from which the skydivers will be dropped.
4. Use a stopwatch or timing device to measure the time it takes for each skydiver to reach the ground.
5. Have each skydiver perform multiple trials to ensure accurate results.
6. Record the mass and falling time for each skydiver in a data table.
7. Analyze the data to identify any patterns or relationships between mass and falling time.
8. Create a graph to visually represent the data, with mass on the x-axis and falling time on the y-axis.
9. Use statistical analysis (if applicable) to determine if there is a significant difference between the falling times of skydivers with different masses.
10. Draw conclusions based on the data and analyze whether the hypothesis was supported or not.
11. Discuss any limitations or sources of error in the experiment, such as air resistance or variations in body position during the fall.
12. Suggest possible future experiments to further investigate the relationship between mass and falling time.
