![]() ![]() Remember to record measurements to theproper number of significant figures. Data Collection: Complete the data table below. Show one sample calculation onthe next page. Calculate the acceleration due to gravity for each trial. In an experiment to determine the acceleration due to gravity g, the formula used for the time period of a periodic motion is T27(Rr)5g. Return the tennis ball to the height in step 1 and repeat four more times.4. Drop the tennis ball and time its fall using a stopwatch. Recordthe distance from bottom of the ball to the ground, measuring to the nearest wholecentimeter. The gravitational force of the Earth causes all objects to be accelerated towards the center of the Earth. THEORY The force of gravity affects all massive bodies. Hold a tennis ball at a height of two meters, at the ceiling or out of the window. The objective of the lab was to determine the gravitational acceleration constant, g, by measuring the change in velocity of known masses sliding down an inclined plane. Tennis ball, stopwatch, meterstick, marble and Bounce PadMethod 1 – Tennis BallProcedure1.Compare experimental values of acceleration due to gravity with accepted value.Materials.To measure the acceleration due to gravity by two different methods.LibrettoDate Due: _Acceleration Due to GravityPurpose Check it out!Ī feather and a hammer were dropped at the same time on the moon.Name _Honors PhysicsPeriod _Partners:Date _Lab # 6HMrs. The Brainiacs dropped cars to test Galileo's ideas about falling objects. How is the force of gravity on an object related to gravitational acceleration? If the mass of a falling object doesn't affect its motion, why does a feather fall slower that the g ball? 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. Analysis of Results Plot a graph of the 2h/t against t Draw a line of best fit Calculate the gradient - this is the acceleration due to gravity g Assess the. 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. ![]()
