WebThe standard gravity acceleration is 9.81 m/s 2. In the laboratory, conducting some experiments using a pendulum, we obtain four values for g: 9.76 m/s 2, 9.6 m/s 2, 9.89m/s 2, and 9.9m/s 2. The variation in values is the product of errors. http://www.physics.hmc.edu/analysis/fitting.php test ktm e bikes 2021
