Simple Harmonic Motion
Question 1
A mass on a spring is displaced from its equilibrium position. Which graph represents the variation of acceleration with displacement for the mass after it is released?
Graph A
Graph B
Graph C
Graph D
Question 2
The four pendulums shown have been cut from the same uniform sheet of board. They are attached to the ceiling with strings of equal length. Which pendulum has the shortest period?
Pendulum A
Pendulum B
Pendulum C
Pendulum D
Question 3
A mass at the end of a vertical spring and a simple pendulum perform oscillations on Earth that are simple harmonic with time period T. Both the pendulum and the mass-spring system are taken to the Moon. The acceleration of free fall on the Moon is smaller than that on Earth. What is correct about the time periods of the pendulum and the mass-spring system on the Moon?
Question 4
An object at the end of a spring oscillates vertically with simple harmonic motion (shm). The graph shows the variation with time t
of the displacement x
of the object.
Answer A
Answer B
Answer C
Answer D
Question 5
A simple pendulum bob oscillates as shown. At which position is the resultant force on the pendulum bob zero?
Position A
Position B
Position C
Resultant force is never zero during the oscillation
Question 6
A mass oscillates with simple harmonic motion (SHM) of amplitude . Its total energy is 16 J.
What is the kinetic energy of the mass when its displacement is
?
