In this lesson, we will practice describing simple harmonic motion quantitatively and defining its parameters such as amplitude, frequency, and phase.
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.
A tyre has a tread pattern in which a crevice occurs every 3.50 cm along the tyre's circumference. Each crevice makes a single vibration as the tyre moves. What is the frequency of these vibrations if the car moves at a speed of 41.0 m/s?
- A 1.17 Hz
- B 0.0854 Hz
- C 11.7 Hz
- D 1â€‰170 Hz
- E 1â€‰440 Hz
What is the period of 73.0 Hz electrical power?
How is the frequency of an oscillation related to the oscillation’s period ?
A radio station broadcasts at 89.2 MHz. What is the duration of one cycle of the primary oscillation?
