Of the two waves presented, which wave has the greatest energy?

• Top wave (higher frequency/shorter wavelength)

• Bottom wave (lower frequency/longer wavelength)

• Both waves have the same amplitude, therefore the same energy.

What is the unit for the period of a pendulum?

• second

• meter

• m/s/s

• Newton

As a pendulum gets longer, what happens to the period?

• doesn't change

• decreases

• increases

Which of these does not affect the period of a pendulum?

• length

• gravity

• mass

Which would have the longest period?

Pendulum A: A 200-g mass attached to a 1.0-m length string

Pendulum B: A 400-g mass attached to a 0.5-m length string

• A

• B

• Same

Which of the following affects the period of a pendulum?

• mass

• length of the string

• tension of the string

• shape of the mass on the string

What is the period of a pendulum

• how many times the pendulum swings before it stops

• how many times the pendulum passes a point in one second

• one complete cycle (complete to and fro motion)

• one complete cycle bouncing up and down

Pendulum "A" is on Jupiter Pendulum "B" is on the Moon.  The Moon has less gravity than  Jupiter the pendulums have the same mass and length.  Which Pendulum has the greater period?

• A

• B

• Same

What is the relationship between period and frequency?

• Period is the inverse of frequency

• Period is equal to frequency

• Period is double the frequency

• Period is half the frequency
