VI. Answers to Questions
1. What is the effect to the result of acceleration when you lower the height of ballistic ball? The effect to the result of acceleration when the height of ballistic ball was lowered was the result of acceleration increases based on the experiment every time the ballistic ball goes down.
2. What possible reasons do you think will affect the validity of your data? Explain your answer. The time and the height of the ballistic ball, whenever height of the ballistic ball was lowered the time of falling ball decreases.
3. What can you say about the results of the theoretical value of "g" to the experimental value of "g"? is your experiment successful or not? explain your answer. The theoretical value of "g" has a big different in the experimental value of "g". Our experiment is successful because we accomplished the objective of this experiment.
4. What conclusion can you draw from the experiment. The
