- A pendulum is a mass hanging from a point so that the mass can swing free.
- The pendulum is basically a string with a weight at one end.
- A bob is the mass hanging of the end of the string
- Each pendulum has its own time period in which it takes to swing through the arc twice, in other words for it to swing back to its starting point
- the frequency of the pendulum is the number of times it swings in a certain length of time.
- Shorter pendulums have a higher frequency and therefore a shorter period than longer pendulums.
- The pendulum swings due to the force of gravity
- Once the bob reaches the bottom of the arc it continues to swing to an equal height of the original position due to momentum.
- A metronome is a type of pendulum used to keep time in music
- Galileo was the first person to examine the pendulums characteristics.
- The pendulum was perfected by many researchers.
