摘要

通过测量摆动周期，使用悬挂的摆锤来确定当地的重力加速度 g。当将系统建模为简摆或物理摆时，发现随着摆锤尺寸的增大，测得的 g 小于公认值。在给定摆锤尺寸的情况下，单摆测得的 g 略高于物理摆。

Pendulum with a large bob

By measuring the period of oscillations, a suspended bob is used to determine the local gravitational acceleration g. When modelling the system as either a simple pendulum or a physical pendulum, the measured g is found to be less than the accepted value as the size of the bob increases. With a given bob’s size, the simple pendulum measures g to be slightly higher than the physical pendulum does.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
