Acceleration Due to Gravity Name: Group Members (if any): This lab entails collecting data by measuring the height from which the object will be dropped and accurately recordin release until it hits the floor. This lab focuses on collecting accurate data in order to calculate the value for acceleratio accepted value for acceleration due to gravity, g = 9.8 m/s^2. Students will select three heights that differ by more than minimum height will be 1.0 meters. Students will record five times for each drop height and find the average time. The height will be used to calculate the value for gravity. The student will then calculate the percent error of the value calcu value for acceleration due to gravity. Using the following equation of motion: where s is the height, v0 is the initial velocity of the obje the acceleration. Since gravity is an acceleration, not a force, substituting g for a provides a mathematical equation for for acceleration due to gravity. A dropped object has an initial velocity equal to zero. This fact simplifies the equation t Solve the equation for g below to determine the variables needed to calculate a value for acceleration due to gravity. g=? Outcomes: 1. The student will cacluate an experimental value for acceleration due to gravity. 2. The student will compare the calculated value to the accepted value for acceleration due to gravity. 3. The student will calculate the percent error of the experimental value compared to the accepted value. Materials: 1 1 1 1 Ball Stop Watch that can measure less than one second. Recommended: Use timer on your computer or cell pho Tape Measure Phone or camera to take a photo of your setup Safety Points: 1. Small parts are involved, keep them from small children or animals. 2. Don’t leave materials scattered on the floor, trip hazard. 3. Be aware of your surroundings, make sure the space is clear for the ball to bounce. Procedure: Measure the time it takes for a ball to drop from three different heights. Take five time trials and find the average time. Place you provided. SHOW CALCULATIONS.
