The study of physics allows us to make predictions based on previous data. In this introductory practical you will collect data then make a prediction, within a range of uncertainty, based upon your data.
Goal:
Goal:
Create a model to predict the height of a ball, the given a random height and a specified bounce.
Example:
Example:
A height of 1.20m and the third bounce was assigned to your group. Can you predict the hight the ball will reach? (Max height between a3 and a4)
Materials:
Materials:
Ball of your choice (from given samples)
Meter Sticks / Tape measures
Choice of Surface
Stopwatch (your phone)
Video camera (your phone)
Cell Phone stand
Any other material you may need.
Procedure:
Procedure:
You will have 25 min to develop your model to predict the height of the bouncing ball. Your model must account for varying heights and multiple number of bounces.
Using the table to the left, describe what quantities you will be measuring, the symbol you will use to represent the quantity, the units of measure you will be using and the equipment you will need to measure the quantity.
After 25 min, you will be assigned a height to drop the ball from and a bounce to predict the height.
Your group will then have time to determine a predicted height of the given bounce.
Prior to dropping the ball, you will explain how you arrived at the predicted height of the given bounce to the class.
Be prepared to support your prediction with evidence collected in class.
Using your data, provide a range ± x.xx meters for the accuracy of your prediction.
Spin the Wheel to determine your initial height.
Spin the Wheel to determine your bounce number.
