Understanding the Conservation of Energy: Ball and Pendulum Dynamics

This educational overview explores the concepts of energy conservation through the examples of a ball dropped from a cliff and a pendulum's motion. It identifies key principles such as kinetic and potential energy, illustrating when a ball moves fastest at the lowest point and slowest at the highest point. The pendulum's energy dynamics are examined, highlighting the transitions between gravitational potential energy and kinetic energy during its swing. These demonstrations emphasize that total energy remains constant, providing a foundational understanding of energy conservation in physics.

  1. Conservation of Energy (E)

  2. Energy (E) means Total Energy Conservation of Energy (E)

  3. Drop a Ball off a Cliff

  4. Drop a Ball off a Cliff When is the ball moving the fastest? at the lowest point * * just before it hits the grounds and just after

  5. Drop a Ball off a Cliff When is the ball moving the fastest? at the lowest point * When is the ball moving the slowest? at the highest point (it has to stop in order to change directions)

  6. Drop a Ball off a Cliff When is the ball moving the fastest? at the lowest point * When is the ball moving the slowest? at the highest point What is the ball trading for speed? height
