All Flashcards
What is the effect of applying an external force at the natural frequency of a system?
Resonance occurs, leading to a dramatic increase in the amplitude of oscillation.
What is the effect of increasing the spring constant (k) on the period of oscillation?
The period of oscillation decreases.
What is the effect of increasing the mass (m) on the period of oscillation?
The period of oscillation increases.
What is Simple Harmonic Motion (SHM)?
Oscillations that follow a smooth, repeating pattern (sine or cosine wave).
Define Amplitude (A) in SHM.
The maximum displacement of an object from its equilibrium position.
Define Frequency (f) in SHM.
The number of oscillations per unit time.
What is Angular Frequency (ω)?
A measure of the oscillation rate, related to frequency by ω = 2πf.
Define the Phase Constant (φ) in SHM.
Determines the initial position of the oscillating object at time t = 0.
What is Resonance?
The phenomenon where the amplitude of an oscillation increases dramatically when an external force is applied at the system's natural frequency.
What is Natural Frequency?
The frequency at which a system oscillates freely without any external force.
Define Period (T) in SHM.
The time taken for one complete oscillation.
What is the definition of Amplitude (A)?
The maximum displacement from the equilibrium position.
What is the definition of Frequency (f)?
The number of oscillations per second, measured in Hertz (Hz).
What is the definition of Period (T)?
The time it takes for one complete oscillation.
Define Simple Harmonic Motion (SHM).
Back-and-forth motion around an equilibrium point, characterized by periodic changes in displacement, velocity, and acceleration.
What is displacement in the context of SHM?
The distance of an object from its equilibrium position at a given time.
