Question
A body undergoes simple harmonic motion. Which graph correctly shows the variation with displacement x of the velocity v of the body?
Markscheme
A
Examiners report
Sinusoidal graphs are only generated in SHM when time is on the x-axis. Hence B and C are incorrect. D should be well-known to the candidates as the definition of SHM, but can be ruled out as it shows zero v when x = 0. Hence, by elimination, it must be A.
