![]() ![]() Why did you have to be careful to throw the ball horizontally? What would have happened if you accidentally gave the ball a slightly upward initial velocity? What about a slightly negative initial velocity? Finally, if you saw that all objects fall at the same rate, you have verified Galileo's experiment – just like he supposed did at the Tower of Pisa. Did you discovered that regardless of the speed you threw the ball horizontally the time of the fall was the same? If so, you have shown that the horizontal motion does not affect the vertical motion. If you found that the time for the fall was about 0.45s, then you have verified the accepted value of the acceleration due to gravity is 9.8m/s 2. Comment on your results compared with your prediction. ![]() 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 decrease if the G-ball is thrown faster.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.
