PHY 121 - Chapter 11 Question and
answers verified to pass 2025
Periodic motion is sometimes called - correct answer ✔simple harmonic
motion.
All periodic motion shows a displacement proportional to - correct answer
✔the applied force
The most common example of simple harmonic motion is the - correct
answer ✔pendulum
The period is independent of the size of the angle and the mass. It is
dependent on the - correct answer ✔length
ll vibrating systems or objects have a natural vibrating frequency called -
correct answer ✔the resonant frequency.
When an object reaches its resonance frequency it requires very little energy
to - correct answer ✔continue the vibrations.
A wave transports energy from one location to another by - correct answer
✔vibrating the molecules of the medium.
amplitude - correct answer ✔the maximum displacement of the molecules in
the medium from their equilibrium positions ( in meters, symbolized byA)
wavelength - correct answer ✔the horizontal distance between two similar
points on a wave (in meters, symbolized by l )
