CHAPTER QUIZ 2 (Waves and Optics)

In Simple Harmonic Motion, when will the magnitude of velocity be at its maximum?

• At stretched phase only

• At compressed phase only

• At stretched and compressed phase

• At equilibrium point

A mechanical system that exhibits periodic motion, which is composed of a particle-like bob suspended by a light string suspended at the upper-end.

• Damped Oscillation

• Spring-mass system

• Simple Pendulum

• Physical Pendulum

Which of the following conditions is considered so that we may identify a system as motion under simple harmonic?

• It should have the presence of a retarding/ dissipative force

• If there is a force that is always directed at the equilibrium position

• If the system is always at the equilibrium position

• If the system is constantly moving away from the equilbrium position

It is defined as the dramatic increase in the amplitude near the natural frequency.

• Frequency

• Wavelength

• Resonance

• Damping

Which of the following is NOT an example of Periodic Motion?

• An oscillating spring-block system

• A ball falling to the ground.

What best describes a periodic motion?

• Any movement of an object that is repeated in a given length of time.

• Any circular motion.

• Any movement of an object that has consistent patterns.

• Any movement that is predictable and continues forever.
