Repeat this several times until you are sure which one hits the ground first.Drop a G-ball and a baseball from the same height at the same time.Do the values vary more than they did for the dropped G-ball? Comment on your results and compare them with your prediction.Repeat this tossing the ball horizontally at several different speeds.Time the fall for the G-ball tossed horizontally from a height of 1.0m.Comment on your value compared with your prediction.Repeat this process several times to get an average value.Following the instructions packaged with the G-ball, use it to time a fall of 1.0m.If you drop a G-ball and a baseball/softball at the same time which one will hit the ground first? Again, take a moment to write down your thinking to explain your answer. Take a moment to write down your thinking and explain your answer.
The time for the fall will stay the same if the G-ball is thrown faster.The time for the fall will increase if the G-ball is thrown faster.If you toss the G-ball horizontally, at different speeds do you think: Use the accepted value of g = 9.8m/s 2 and the kinematic equation to predict the time of fall. Finally, you will drop the G-ball and a baseball to see which object accelerates more rapidly.Īssume that you drop the G-ball from rest from an initial height of 1.0m. Next, you'll throw the G-ball horizontally at different speed and see if the time of fall changes. You need a G-Ball, a meter stick, and other objects to drop such as a baseball/softball.įirst, you will measure the acceleration due to gravity by simply dropping the G-ball and getting the time to fall. Using the G-Ball by Arbor Scientific, you can measure this value and compare the acceleration of other objects with different masses and in different states of motion. Modern measurements indicate that this gravitational acceleration is about 9.81m/s 2. Galileo claimed that all objects fall toward Earth with the same acceleration.
