QUESTIONS AND SOLUTIONS


◉Stopping Potential. Answer: The work done by the potential
difference in stopping the fastest moving electrons


◉Electron Volt. Answer: The kinetic energy that an electron has
after being accelerated from rest through a potential difference of 1
volt


◉1 eV =. Answer: 1.6x10^-19 Joules


◉Ground State. Answer: The lowest energy level that an electron
can occupy in an atom (n=1)


◉Excitation. Answer: When an electron gains the exact amount of
energy needed to move up to a higher energy level in an atom


◉Ionisation. Answer: The process when an electron gains enough
energy from a photon to leave the ground state of the atom that it's
in

, ◉Ionisation Energy. Answer: The amount of energy needed to
remove an electron from the ground state of an atom


◉Radian. Answer: The angle that is equal to the arc length divided
by the radius of the circle 2pi radians = 360 degrees


◉Angular Speed. Answer: The angle an object rotated through per
second (omega = 2pi x frequency)


◉Frequency. Answer: The number of complete revolutions per
second


◉Light Damping. Answer: Stops oscillations over many time periods
(just air resistance etc)


◉Heavy Damping. Answer: Stops oscillations in few time periods,
amplitude gets much smaller each period (like adding a parachute or
something)


◉Over Damping. Answer: Stops oscillating over 1 time period but
takes longer to return to equilibrium (eg toilet seat)
