using motion equations and showing your steps, calculate the acceleration of the ball for each row in the above table. You will get a total of five accelerations

(2)Determine the average of the five accelerations. The average acceleration will be the Experimental Acceleration. Usually, it is denoted by the letter E (E is used to indicate that it is an experimental acceleration). The Actual Acceleration is denoted by the letter A. The actual free-fall acceleration on Earth is A =9.8 m/s²

Percent error =(Actual-Experimental)/Actual X 100 % = (A-E)/A X 100 %

(3) Calculate the percent error between the value you obtained for experimental acceleration (E ) and the actual acceleration A= 9.8 m/s²

VI. QUESTIONS:

1. If this experiment is done on the Moon, will the ball's falling times increase or decrease ? Why ?

2. Using the data from the first-row, calculate the final velocity (V_f) of the ball just before it strikes the ground.

3. If the ball was a large plastic ball having a large surface area and air resistance was considered, will the falling times indicated on the table increase or decrease? Explain

VII. Sources of Error: What are the possible sources of error for this experiment?

VIII. Conclusions: Write down your conclusions. In your conclusions describe if you achieved your objectives and what you have learnt from the experiment.
