The Physics of Disc Golf | Understanding the Forces at Play

Air Resistance: Also known as drag, air resistance is the force that opposes an object''s motion through the air. When a disc is thrown, it pushes air out of its way, causing air resistance. The resistance force depends on the disc''s speed, surface area, and the air''s density. The faster the disc goes or the larger its surface area, the ...

A Review of Flywheel Energy Storage System Technologies

Abstract: The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power.

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th…
