Spring and Pendulum Concepts

100

I am what Hooke's Law states is directly proportional to the amount a spring is compressed.

What is force?

200

This is the place in a pendulum where velocity is at a maximum and the acceleration and net force are zero.

What is equilibrium position?

300

I'm not very massive, but I'm the only thing the period of a pendulum is dependent upon.

What is the length?

400

This is the name for motion of a spring or mendulum that repeats over regular time intervals.

What is the period?

500

This is the name for when a mass on a spring will oscillate.

What is the simple harmonic motion?

Waves Concepts

100

Mechanical waves require this in order to travel from place to place.

What is a medium?

200

This is when two waves get added together and create a larger wave.

What is constructive interference?

300

In a standing wave, this is the part where it appears as if there is No motion.

What is a node?

400

This type of wave occurs when the matter moves perpendicular to the motion of the wave.

What is a transverse wave?

500

To measure me, there must be one complete crest and one complete trough.

What is a wavelength?

Sound Concepts

100

Sound travels in this type of wave.

What is a longitudinal/compressional wave?

200

Distance from a sound affects this, assuming sounds radiate equally in all directions.

What is intensity?

300

This is the name for the first harmonic, it is the lowest possible frequency of a instrument.

What is fundamental frequency?

400

The wah-wah sound speed corresponds to this between two frequencies.

What is a difference of frequency?

500

When a sound is moving towards a detector it will sound as if it is this.

What is a higher pitch?

Springs and Pendulums Math

100

Write the equation that relates force, spring constant, and displacement for a spring.

What is F=-kx?

200

A spring has a spring constant of 200 N/m. How much force is required to stretch it 0.10 m?

What is 20 N?

300

A pendulum completes one full swing every 2.0 s. What is its length of the arm?

What is ~1.01m?

400

If the mass on a spring is increased, this is what happens to the period of the spring–mass system?

What is the period increases?

500

A spring stretches 0.25 m when a force of 50 N is applied to it.
What is the spring constant of the spring?

What is 200 N/m?

Waves and Sound Math

100

Write the wave equation that relates speed, wavelength, and frequency.

What is v=fλ?

200

A wave has a frequency of 5 Hz and a wavelength of 2 m. What is its speed?

What is 10 m/s?

300

A sound wave travels at 340 m/s with a frequency of 170 Hz. What is its wavelength?

What is 2.0 m?

400

If the frequency of a wave increases while speed stays the same, what happens to wavelength?

What is wavelength decreases? 

500

A wave travels 24 m in 6 s. If its wavelength is 3 m, what is its frequency?

What is 1.33 Hz?
