Worksheet: Simple Harmonic Motion

In this lesson, we will practice describing simple harmonic motion quantitatively and defining its parameters such as amplitude, frequency, and phase.

Q1:

Reciprocating motion uses the rotation of a motor to produce linear motion back and forth, as in the operation of the reciprocating saw shown in the diagram. If the motor rotates at 84 Hz and has a radius of 1.9 cm, find the maximum speed of the saw blade during its back and forth motion.

Q2:

A tire has a tread pattern in which a crevice occurs every 3.50 cm along the tireβs circumference. Each crevice makes a single vibration as the tire moves. What is the frequency of these vibrations if the car moves at a speed of 41.0 m/s?

Q3:

What is the period of 73.0 Hz electrical power source?

Q4:

Find the frequency of a tuning fork that takes s to complete one oscillation.

Q5:

How is the frequency of an oscillation related to the oscillationβs period ?

• A
• B
• C
• D
• E

Q6:

A radio station broadcasts at 89.2 MHz. What is the duration of one cycle of the primary oscillation?
