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

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

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.

For a system in simple harmonic motion, which of the following is the time required to complete a cycle of motion?

• amplitude
• period
• frequency
• revolution

In simple harmonic motion, the displacement is maximum when the: 

• acceleration is zero 
• velocity is maximum 
• velocity is zero 
• kinetic energy is maximum 

A mass attached to a spring vibrates back and forth. At the equilibrium position, the

• acceleration reaches a maximum.
• velocity reaches a maximum.
• net force reaches a maximum.
• velocity reaches zero.

As a pendulum gets longer, what happens to the Period?

• increases

• doesn't change

• decreases

• constant

How are frequency and period related in simple harmonic motion?

• They are directly related.
• They are inversely related.
• Their sum is constant.
• Both measure the number of cycles per unit of time.
