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. WebOct 9, 2024 · The major challenges are organising the practical apparatus within their school and having sufficient time within a laboratory to undertake enough practical work during the course.
