Study Notes
Potential and Kinetic Energy Concepts
-
Elastic Potential Energy in a Bow and Arrow: Stretching the bow stores elastic potential energy, which transforms into kinetic energy upon release, propelling the arrow.
-
Potential Energy in Roller Coasters: The maximum potential energy occurs at the highest point of a roller coaster; it shifts to kinetic energy as the cars descend.
-
Energy Conservation in Roller Coasters: Total mechanical energy (potential + kinetic) remains constant while their individual amounts fluctuate during the ride.
-
Boulder's Potential Energy: A stationary boulder atop a mountain possesses significant potential energy due to its height and mass. Its potential energy can have dangerous consequences if released.
-
Kinetic Energy of a Skateboarder: As a skateboarder descends a hill, potential energy is converted into kinetic energy, increasing speed.
-
Elastic Potential Energy in a Rubber Band: Stretching a rubber band stores potential energy, which is released as kinetic energy upon release.
-
Gravitational Potential Energy in a Swing: At the highest point (point A), potential energy peaks and kinetic energy bottoms out. Conversely, at the lowest point (point B), kinetic energy reaches its maximum while potential energy is minimal.
-
Work Utilization of Potential Energy: Gravitational potential energy in a heavy weight is converted into kinetic energy for performing work, such as driving a stake into the ground.
-
Pendulum Energy Conversion: A pendulum converts potential energy to kinetic energy as it swings down. At the lowest point, kinetic energy is maximized, enabling the swing back up and regaining potential energy.
-
Ball Toss Energy Transition: Tossing a ball upward adds kinetic energy, which converts into potential energy at the peak. As the ball falls, potential energy is converted back into kinetic energy due to gravity.
