AQA Physics (7407, 7408) A-level SHM-Questions andAnswers
motion of an object if its acceleration is proportional to the displacement of the object from
equilibrium and is always in the opposite direction to displacement Correct Ans-what is
simple harmonic motion
pendulum and mass-spring system Correct Ans-2 examples of SHM
at equilibrium positon Correct Ans-when is velocity at it's maximum
at maximum displacement Correct Ans-when is when is velocity 0
at maximum displacement in the opposite direction Correct Ans-when is acceleration
maximum
the displacement from the equilibrium position to the maximum displacement Correct
Ans-what's the amplitude of a SHM
, AQA Physics (7407, 7408) A-level SHM-Questions and
Answers
the number of cycles per second Correct Ans-what is frequency
2π/T or 2πf where T is time period and f is frequency Correct Ans-what is angular
frequency w
for 2 objects oscillating with the same time period, T, the phase difference is 2π*t/T, where t
is the time between successive instants when two objects are at maximum displacement in
the same direction Correct Ans-what is phase difference
multiply by 360/2π Correct Ans-how to convert radians to degrees
x = A*cos(w*t)
where A is the amplitude, w is the angular frequency and t is time Correct Ans-what is
displacement,x, equal to when is starts from maximum amplitude
