WebIn this science fair project, you will investigate how the period of a pendulum is related to the pendulum's length. A pendulum's period is the time it takes the pendulum to swing back to its original position. In the example of a kid being pushed in the swings at a playground, this is the time it takes the kid to be pushed and then return back ... WebThe Challenger Disaster. After the space shuttle Challenger and its crew were destroyed in a fiery, catastrophic explosion on January 28, 1986, NASA appointed members of the Rogers Commission to investigate the cause of the disaster. When he was asked to be a part of this commission, Feynman rather reluctantly accepted.

When the bob of pendulum is released from point ‘A’, the velocity of bob increases gradually, while the height of bob is decreasing accordingly to it. At point ‘M’, velocity will become maximum and the height will be equal to zero.
