Chapter 7 Simple Harmonic Motion

What is the equation for frequency?

• f = t/n
• f = 1/T
• f = 2 T

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 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 number of cycles or oscillation made in one second is defined as

• time taken

• period

• frequency

• amplitude

When is the pendulum at maximum velocity

• At its lowest point

• At its highest point

• It moves at a constant velocity

• It is at rest

When does the mass move at maximum velocity in a mass-spring system?

• At equilibrium

• At the farthest point from the equilibrium

• At its hightest point

• At its lowest point

What are the two requirements for a simple harmonic oscillator?

• The object vibrates about the equilibrium point and the restoring force is proportional to the displacement

• The object moves left to right and the restoring force is proportional to the displacement

• The object vibrates about the equilibrium and the restoring force is greater than the displacement

• The object moves left to right and the restoring force is greater than the displacement

When is the pendulum at 0 velocity

• At its lowest point

• At its highest point

• It moves at a constant velocity

• It is at rest

When does the mass move at 0 velocity in a mass-spring system?

• At equilibrium

• At the farthest point from the equilibrium

• At its hightest point

• At its lowest point
