Study Notes
Simple Harmonic Motion Concepts
- Doubling the displacement in simple harmonic motion results in a quadrupling of elastic potential energy, as elastic potential energy is proportional to the square of the displacement.
- Simple harmonic motion features a restoring force that is directly proportional to the displacement from the equilibrium position, following Hooke's Law.
Pendulum Dynamics
- Shortening a pendulum decreases its time period of oscillation, leading to a faster frequency due to the relationship between length and time period (T = 2π√(L/g)).
Mass and Frequency Relationship
- Doubling the mass of an oscillating system, while keeping other factors constant, results in a decrease in frequency, as frequency is inversely proportional to the square root of mass.
Properties of a Spring
- The force constant (k) of a spring quantifies its stiffness, expressed as the ratio of the force exerted on it to the displacement produced (k = F/x).
Time Period in Motion
- In simple harmonic motion, the time period represents the duration of one complete cycle, providing insight into the oscillation rate.
Types of Oscillations
- Free oscillation occurs in an undamped system where oscillations continue indefinitely, while damped oscillation experiences a gradual reduction in amplitude due to external resistance or friction.
Angular Harmonic Oscillation
- Angular harmonic oscillation refers to the motion of an object in a circular path where the acceleration is directed towards a central point, exhibiting periodic behavior similar to linear harmonic oscillation.
