CIE A Level Physics復習筆記18.1.3 Electric Field Strength
Electric Field Strength The electric field strength of a uniform field between two charged parallel plates is defined as: Where: E =?electric field strength?(V m-1) ΔV = potential difference betwee...
CIE A Level Physics復習筆記18.1.2 Electric Field Lines
Representing Electric Fields The direction of electric fields is represented by electric field lines Electric field lines are directed from positive to negative Therefore, the field lines must be p...
CIE A Level Physics復習筆記18.1.1 Electric Fields & Forces on Charges
Electric Field Definition An electric field is a region of space in which an electric charge “feels” a force Electric field strength?at a point is defined as: The electrostatic force per unit posit...
CIE A Level Physics復習筆記17.2.2 Resonance
Resonance In order to sustain oscillations in a simple harmonic system, a periodic force must be applied to replace the energy lost in?damping This periodic force?does work?on the resistive force d...
CIE A Level Physics復習筆記17.2.1 Damping
Damping In practice, all oscillators eventually stop oscillating Their amplitudes decrease rapidly, or gradually This happens due to?resistive forces, such friction or air resistance, which act in ...
CIE A Level Physics復習筆記17.1.6 Energy in SHM
Kinetic & Potential Energies During?simple harmonic motion, energy is constantly exchanged between two forms: kinetic and potential The potential energy could be in the form of: Gravitational p...
CIE A Level Physics復習筆記17.1.5 SHM Graphs
SHM Graphs The displacement, velocity and acceleration of an object in?simple harmonic motion?can be represented by graphs against time All undamped SHM graphs are represented by?periodic functions...
CIE A Level Physics復習筆記17.1.4 Calculating Speed in SHM
Calculating Speed of an Oscillator The speed of an object in?simple harmonic motion?varies as it oscillates back and forth Its speed is the magnitude of its velocity The greatest speed of an oscill...
