1. What is the definition of a pendulum's period?
The total distance it travels.
The time it takes for one complete swing back and forth.
The height from which it is released.
The mass of the pendulum bob.
2. Which of the following factors primarily affects 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.
3. Describe the energy transformations that occur in a swinging pendulum.
4. At the highest points of its swing, a pendulum has maximum energy and minimum energy.
5. The point where a pendulum is at rest in the center of its swing is called the position.
6. Increasing the mass of a pendulum bob will increase its period.
True
False
