Question
Objective: Determine the acceleration due to gravity
Materials:
• Tennis ball
• Meter stick
• Stopwatch
Procedures:
• One student in the group will be the ball dropper.
• One student will be the timer and run the stopwatch.
• One student will be the recorder.
• Determine a method to drop the tennis ball from a height of 1.5 meters, each time the ball is dropped.
• Drop the ball from the 1.5 meter height for 10 trials. Record the time it takes for the ball to hit the ground.
• Calculate the average time using your data table.
Student Data can be seen in the table above.
Each student group ran 10 trials. Measuring a single item or event more than once is done for ALL BUT ONE of the reasons listed here,
Responses
A Repeating an experiment more than once helps determine if the data was a fluke.Repeating an experiment more than once helps determine if the data was a fluke.
B Repeating measurements is helpful in cases where the measurement is challenging to make.Repeating measurements is helpful in cases where the measurement is challenging to make.
C Repeating measurements help to avoid experimental bias, the favoring of one outcome over another.Repeating measurements help to avoid experimental bias, the favoring of one outcome over another.
D More measurements of a single event lead to greater confidence in calculating an accurate average measurement.
