Physics of Oscillations: Simple Pendulum and Spring
Oscillations are fundamental phenomena in physics characterized by repetitive motions. In this brief video, we will examine the oscillations produced by a simple pendulum and a spring. We will discuss how to calculate the period of these oscillations using formulas, as well as how to measure the period experimentally. By comparing the calculated and measured values, we can verify the accuracy of our theoretical predictions.
Simple Pendulum
A simple pendulum consists of a mass (known as a bob) attached to the end of a lightweight cord, which is fixed at its other end. When displaced from its equilibrium position and released, the pendulum oscillates back and forth under the influence of gravity.
Spring-Mass System
A spring-mass system consists of a mass attached to a spring. When the mass is displaced from its equilibrium position, it oscillates back and forth due to the restoring force exerted by the spring.
By understanding the principles of oscillations and accurately measuring periods, students can gain valuable insights into harmonic motion. These experiments with simple pendulums and spring-mass systems provide a hands-on approach to verifying theoretical predictions in physics.
