The total kinetic energy of a system depends on the inertial frame of reference: it is the sum of the total kinetic energy in a center of momentum frame and the kinetic energy the total mass would have if it were concentrated in the center of mass.
In fluid mechanics, Kelvin's minimum energy theorem (named after William Thomson, 1st Baron Kelvin who published it in 1849 [1]) states that the steady irrotational motion of an incompressible fluid occupying a simply connected region has less kinetic energy than any other motion with the same normal component of velocity at the boundary (and, if the domain extends to infinity, with zero value ...
Sample from a kinetic energy weapon test. A piece of polycarbonate plastic weighing 7 grams ( 1 ⁄ 4 oz) was fired at an aluminium block at 7 km/s (23,000 ft/s), giving it muzzle energy of 171,500 J (126,500 ft⋅lbf); a typical bullet has muzzle energy of a few thousand joules, with the enormous .950 JDJ reaching 20,000 J (15,000 ft⋅lbf).
The concept of a gravitational slingshot is a form of propulsion to carry a space probe onward to other destinations without the expense of reaction mass; harnessing the gravitational energy of other celestial objects allows the spacecraft to gain kinetic energy. [80]
An aero engine inertia starter uses a pre-rotated flywheel to transfer kinetic energy to the crankshaft, normally through reduction gears and a clutch to prevent over-torque conditions. Three variations have been used, hand driven, electrically driven and a combination of both.
Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient.An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H +) across a membrane during cellular respiration or photosynthesis.
A kinetic energy recovery system (KERS) is an automotive system for recovering a moving vehicle's kinetic energy under braking. The recovered energy is stored in a reservoir (for example a flywheel or high voltage batteries) for later use under acceleration.
A flashcard or flash card is a card bearing information on both sides, usually intended to practice and/or aid memorization. It can be virtual (part of a flashcard software ) or physical. Typically, each flashcard bears a question or definition on one side and an answer or target term on the other.
