Mechanics
The type of acceleration experienced by an object moving in a circle at a constant speed, directed toward the center of the circle.
What is centripetal acceleration?
The phenomenon where waves bend around obstacles or spread out after passing through narrow slits.
What is diffraction?
The rate at which electrical energy is transferred in a circuit, calculated as P=VI.
What is electrical power?
he subatomic particle with no electric charge located inside the atomic nucleus, discovered by James Chadwick in 1932.
What is a neutron?
GUESS
How do you solve Physics problems?
This quantity, measured in kilogram meter-squared (kgm2), is the rotational equivalent of mass.
What is the rotational inertia?
The apparent change in frequency or wavelength of a wave observed by someone moving relative to the wave source.
What is the Doppler Effect?
The opposition to alternating current (AC) in a circuit containing resistors, capacitors, and inductors combined.
What is impedance (Z)?
The packet or quantum of electromagnetic energy whose energy is given by E=hf
What is a photon?
The Last Jedi
What is the worst Star Wars movie of all time?
According to this law, the total angular momentum of a rotating system remains constant if no external net torque acts on it.
What is the law of conservation of angular momentum?
This type of interference occurs at points where two identical waves arrive out of phase by half a wavelength, creating a node.
What is destructive interference?
An electromotive force (EMF) is induced in a conductor when there is a change in magnetic flux over time.
What is Faraday's Law?
The minimum amount of energy required to eject an electron from the surface of a metal in the photoelectric effect.
What is the work function (Phi)?
Manit
Who does Mr Wethey dislike most?
Motion in which acceleration is proportional, but opposite to, displacement.
What is simple harmonic motion (SHM)?
The term for a point along a standing wave where the wave experiences zero amplitude and no vibration due to complete destructive interference.
What is a node?
This occurs in an AC circuit when inductive reactance (XL) and capacitive reactance (XC) are equal in magnitude
What is resonance?
The nuclear reaction in which a heavy nucleus splits into two smaller daughter nuclei, typically triggered by absorbing a slow neutron.
What is nuclear fission?
Electromagnetism (it will be my favourite topic too)
What is Mr Wethey's favourite topic?
When an object executing simple harmonic motion reaches its maximum displacement, these two dynamic quantities reach zero.
What are velocity and kinetic energy?
A standing wave in which the length of the string is exactly half a wavelength.
What is the First Harmonic?
The direction of an induced current will always produce a magnetic field that opposes the change in flux that caused it.
What is Lenz's Law?
This very handsome physicist proposed a model for the hydrogen atom which explained atomic line spectra.
Who is Niels Bohr?
What is the most common thing for Mr Wethey to say at the end a lesson?
Go play in the traffic
