The variable that is measured in an experiment is the dependent variable. What did we measure in the experiment?

• The mass of the pendulum

• The angle of the drop

• The amount of time it took the pendulum to swing 10 times

• The length of the pendulum

We used the amount of time it took the pendulum to swing 10 times to calculate ________________.

• frequency

• period

• wavelength

• amplitude

One pendulum is 0.50m and the other is 1.00m. Which pendulum will have a lower frequency if both are dropped from a 45° angle?

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
