Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. What is the main factor that determines the period of a simple pendulum?
The mass of the bob
The amplitude of the swing
The length of the string
The material of the string
2. At which point in a pendulum's swing is its potential energy highest?
At the bottom of its swing
At the highest points of its swing
Halfway through its swing
It is constant throughout the swing
3. The time it takes for a pendulum to complete one full swing back and forth is called its .
4. As a pendulum swings, energy is continuously transformed between potential energy and energy.
5. Observe the pendulum below. Describe the energy transformations that occur as the pendulum swings from its highest point on one side to its highest point on the other side.
6. Increasing the mass of the bob will increase the period of the pendulum.
True
False
7. Air resistance can cause a pendulum's swing to gradually decrease in amplitude.
True
False
Match the term on the left with its definition on the right.
8. Period
a. The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
9. Amplitude
b. The time taken for one complete oscillation of a pendulum.
10. Bob
c. The mass attached to the end of a pendulum string.
