Systematic Research on Measuring Acceleration of Gravity by Laser Interferometry
Abstract
Gravity acceleration is an important physical quantity, and its precise measurement results have important applications in practice. According to the principle of measuring gravity acceleration in college physics experiment, a scheme of measuring gravity acceleration by laser interferometry is designed, and the main sources and sizes of experimental errors are analyzed and calculated. Compared with the common simple pendulum method and falling body method, the theoretical results show that our measurement method has higher precision and is feasible to accurately measure the acceleration of gravity.
