Study Notes
Harmonic Oscillator
- Spring Constant (k): Related to spring's stiffness, affects oscillation frequency.
- Mass (m): Affects oscillation period.
- Amplitude (A): Maximum displacement from equilibrium.
- Period (T): Time taken for one complete oscillation.
- Frequency (f): Number of oscillations per unit time. Frequency (f) = 1/Period (T)
- Angular Frequency (ω): ω = 2πf = 2π/T
- Maximum Velocity (vmax): vmax = ωA
- Maximum Acceleration (amax): amax = ω²A
- Potential Energy (PE): PE = 1/2k x²
- Kinetic Energy (KE): KE = 1/2 mv²
Specific Examples from Image
- Mass (m): 0.4 kg
- Maximum Acceleration (amax): 2m/s²
- Spring Constant (k): Calculations involving k, A (amplitude is 12cm or 0.12m) and period of oscillation related to motion, will vary in different problems.
- Period (T): Calculation related to period, mass, acceleration, and amplitude. There are several different period calculations in the image corresponding to different situations.
- Amplitude (A): 0.8 cm, calculations are present for the amplitude.
- Maximum force (F): Determined by the spring constant and the amplitude. F = kA.
- Energy Calculations: Calculations for kinetic, potential and total energy of the oscillator are present for different scenarios.
- Position, velocity, and acceleration of oscillator in different phases of the oscillation: Determined by position from equilibrium, related to phase.
Other Calculations
- Calculations for energy conservation in the system: Includes considerations for various parameters affecting energy calculations.
- Calculations for oscillation frequency in different situations: Related to spring constant, mass, and other factors.
- Calculations for various different parameters: Calculations are available for a variety of problems, including spring constants and amplitudes.
General Principles
- Energy Conservation: Total energy (kinetic + potential) remains constant in a simple harmonic motion.
- Equilibrium: The point where the net force is zero.
- Phase: The relative position of a system in its oscillation cycle, affecting calculated characteristics of the oscillator.
- Simple Harmonic Motion (SHM): A special type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium and is directed towards the equilibrium position.
