Schwingungen und Pendel

What is a vibration?

• A movement that goes in only one direction

• A uniform back-and-forth movement around a center

• A circular movement

• A straight line

The time it takes for a pendulum to complete a full back-and-forth movement is called:

Which quantity do we change in the experiment with the pendulum?

• Weight of the pendulum

• Displacement

• Length of the pendulum

• Room temperature

If 10 vibrations take 8.0 seconds, what is the period duration T?

• 80 seconds

• 0.8 seconds

• 8 seconds

• 0.5 seconds

A longer pendulum swings faster than a shorter one.

• True

• False

The longer the pendulum, the __________ the period duration.

If I displace the pendulum further, the period duration will...

• be shorter

• stay the same

• be longer

• be very irregular

Why is the pendulum in a church clock particularly long?

• So it swings faster

• So it looks nicer

• So it swings slower and evenly

• So it weighs less
