Free Fall Laboratory Experiment
Free Fall Laboratory Experiment
Problem/Question - Will two spheres with different masses fall towards earth at the same rate?
Free Fall Laboratory Experiment
Hypothesis - Generate your own hypothesis for this experiment.
Free Fall Laboratory Experiment
Materials/Procedure - - Balance- Small steel sphere- Large steel sphere- Foam pad- Meter stick- Stopwatch
Free Fall Laboratory Experiment
Materials/Procedure - 1) Set up the rubber pad on the floor to catch the steel spheres after they have dropped to the floor.2) Using a meter stick, measure the height of the lab bench where the spheres will be dropped. 3) Choose one partner to drop the ball, one partner to time the drop, one partner to retrieve the ball and one partner to record the data.
Free Fall Laboratory Experiment
Materials/Procedure - 4) Measure the mass of both spheres and record in the data table.5) Practice dropping the ball a few times at a height even with the lab bench.6) When ready, begin recording the data in your data table.7) Complete ten trials for each sphere, recording times in your data table.8) Complete the data analysis and conclusion.
Free Fall Laboratory ExperimentData -
Free Fall Laboratory ExperimentData Analysis - 1) Use the equation: a = 2d/t2 to calculate the acceleration of each drop and record in your data table.2) Use the equation below to calculate the percent error between the measured and accepted values for the acceleration due to gravity for each drop. Use 9.8 m/s2 as the accepted value.
% error = measured value - accepted value accepted value x 100
Free Fall Laboratory ExperimentData Analysis - 3) Calculate the average acceleration for each size ball and enter results in the data table.
Free Fall Laboratory Experiment
Conclusion - Provide a conclusion that includes a description of the relationship between acceleration from gravity and mass.
