shm motion, pendulum

If an object is in oscillatory motion, what must be true if it's in simple harmonic motion? 

• Its motion is along the path of a circle
• acceleration is proportional to the displacement
• Its potential energy is equal to the kinetic energy
• It's attached to a spring

Which of the following is not an example of SHM?

• A simple pendulum
• A vibrating spring
• A marble on a concave surface
• Bouncing on a trampoline

According to Hooke's law, the force exerted by a spring on an object is proportional to...

• the displacement of the spring
• the mass of the spring
• the length of the spring
• the volume of the spring

In any system in SHM, the restoring force acting on the mass in the system is proportional to

• the displacement
• the length of the pendulum
• the mass
• the frequency

The period of a pendulum may be decreased by

• Increasing the mass of the bob
• moving the equilibrium point
• decreasing the mass of the bob
• shortening the length of pendulum

Which of the following statement is true about SHM?

• The maximum acceleration occurs when the velocity is maximum
• The maximum acceleration occurs when its velocity is zero
• If the velocity is zero so is the displacement
• The instantaneous velocity of the mass is never zero

The angle between the string of a pendulum at its equilibrium position and at its maximum displacement is the pendulum’s

• period.
• frequency.
• vibration.
• amplitude.
