Topics, Questions, Examples, and Assignments
Question: Define Oscillatory motion and the terms associated with oscillation.
Example 10.1: What is the frequency of oscillation if the time period is 20 ms?
Assignment 10.1: When an object oscillates with a frequency of 0.5 Hz, what is its time period?
Simple Harmonic Motion
Question: What is simple harmonic motion? Explain the conditions necessary for a body to oscillate with SHM.
SHM … Mass-spring system
Question: What is spring-mass system in Physics? Show that a mass attached to a spring executes SHM.
Question: Derive expressions for the time period and frequency of mass-spring system.
Example 10.2: A spring has a spring constant 48.0 N/m. This spring is pulled to a distance of 55 cm from equilibrium. What is the restoring force?
Assignment 10.2: Determine the restoring force of a spring displaced 1.5 m with the spring constant of 30.0 N/m.
Example 10.3: What is the mass of a vertical mass-spring system if it oscillates with a period of 2.0 s and has spring constant of 20.0 N/m.
Asignment 10.3:A body of mass 0.2 kg is attached to a spring placed on a frictionless horizontal surface. The spring constant of the spring is 4 N/m. Find the time period of the oscillating mass-spring system.
