Lab Objective: Your mission, is to design and conduct an experiment that will allow you to measure the acceleration due to gravity using two photogates and a metal ball.

Materials:

Two photogates

Metal ball (e.g., steel or iron)

Meterstick or ruler

Stopwatch or timer

Lab notebook and pen

Considerations:

What factors might influence the accuracy of your measurements?

How can you ensure the metal ball falls freely without interference?

Data Analysis:

Compare your experimental results with the accepted value of approximately 9.8 m/s29.8m/s2.

Conclusion:

Summarize your findings, discuss any sources of error, and propose improvements for future experiments.
