IB DP Physics: SL復習筆記5.1.5 Coulomb’s Law
Coulomb's Law Any charged particle generates an electric field This field exerts a force on any other charged particle within range The electrostatic force between two charges is defined by?Coulomb...
IB DP Physics: SL復習筆記5.1.4 Electric Fields
Electric Fields An?electric field?is a region of space in which an electric charge “feels” a force It is a vector field The direction of the electric field is the same as the direction of the elect...
IB DP Physics: SL復習筆記5.1.3 Potential Difference & DC
Potential Difference Potential difference is a measure of the electrical potential energy transferred from an electron as it moves between two points in a conductor Potential difference is work don...
IB DP Physics: SL復習筆記5.1.2 Drift Speed
Drift Speed In conductors, only negatively charged (delocalised) electrons are allowed to move between atoms In general, an electric current can arise from the flow of either positive or negative p...
IB DP Physics: SL復習筆記5.1.1 Charge & Current
Charge Charge is measured in?coulombs?(C). One coulomb is defined as: The charge carried by an electric current of one ampere in one second Charge is a?scalar?quantity Electrons?have a?negative cha...
IB DP Physics: SL復習筆記4.5.4 Harmonics
Harmonics Stationary waves can have different wave patterns, known as?harmonics These depend on the?frequency?of the vibration and the?boundary conditions?(i.e. fixed and/or free ends) The harmonic...
IB DP Physics: SL復習筆記4.5.3 Boundary Conditions for Standing Waves
Boundary Conditions Stationary waves can form on strings or in pipes In both cases, progressive waves travel in a medium (i.e. the string or air) and superimpose with their reflections The number o...
IB DP Physics: SL復習筆記4.5.2 Nodes & Antinodes
Nodes & Antinodes A standing wave is made up?nodes?and?antinodes Nodes?are locations of?zero amplitude?and they are?separated by half a wavelength?(λ/2) Antinodes?are locations of?maximum ampli...
