Study Notes
Physics 2: Second Quarter Reviewer
- Pendulum: A simple pendulum consists of a small object (bob) suspended from a lightweight cord or rod. Its motion, in an isolated system, resembles simple harmonic motion (SHM).
-
Pendulum - Definition of Terms:
- Period: The time it takes for one complete cycle of the pendulum's oscillation
- Angular Displacement: The angle between the pendulum's current position and its equilibrium position. The angle is usually measured in radians.
- Massless Wire: An ideal, non-deforming wire that does not contribute to the pendulum's mass.
- Equilibrium Position: The lowest point of the pendulum's swing
- Pendulum Derivation of Period: The period of oscillation is directly proportional to the square root of the length of the pendulum divided by the acceleration due to gravity
- Pendulum Properties: If the angular displacement θ is small, the restoring force can be approximated, and the period (T) of a simple pendulum is given by T = 2π √(L/g).
- Waves: Distrubances that transfer energy without net matter displacement.
-
Two Types of Waves:
- Mechanical Waves: Require a medium to transfer energy (e.g., longitudinal, transverse, surface waves)
- Non-Mechanical Waves: Do not require a medium to transfer energy (e.g., electromagnetic waves, gravitational waves).
-
Waves - Properties:
- Amplitude (A): Maximum height of a wave or depth of a trough
- Wavelength (λ): Distance between two successive crests or troughs
- Period (T): Time elapsed between two successive crests passing a given point
- Frequency (f): Number of cycles passing a given point in a unit interval of time
- Wave Velocity (v): Speed at which wave crests move; v = λf
- Wave Intensity (I): Time-averaged rate of energy transported per unit area perpendicular to the direction of propagation; I = P/A.
- Energy and Intensity Relationship.: Intensity is directly proportional to the square of the amplitude of the wave.
Wave Reflection, Refraction, Diffraction, Interference, Superposition
- Reflection: Change in direction when a wave meets a boundary or barrier; The angle of incidence equals the angle of reflection.
- Refraction: Change in direction when a wave passes from one medium to another (Due to the change in speed of the wave in different mediums)
