Simple Harmonic Motion (Edexcel A Level Physics): Exam Questions

A mass is suspended from a spring and allowed to come to equilibrium.

The mass is displaced vertically and moves with simple harmonic motion.

The graph shows how the resultant force on the mass varies with time.

Which of the following graphs shows how the velocity v of the mass varies with time t over the same time interval?

The graph shows how the displacement of a simple harmonic oscillator varies with time.

Which of the following graphs shows how velocity varies with time for the same oscillator, over the same time period?

 A mass at the end of a spring is set into small amplitude simple harmonic motion.

Which of the following graphs correctly shows the variation of velocity $v$ of the mass with displacement $x$ for one complete oscillation? 

An object undergoing simple harmonic motion has a period $T$ and total energy $E$. The amplitude of oscillations is halved.

Which row of the table gives the new period and total energy of the system?
