A kinetic energy penetrator (KE penetrator) is a weapon that damages a target by slamming into it at high speed using kinetic energy. The most common form is the armor piercing fin stabilized discard sabot (APFSDS), used to penetrate tank armor. The US military developed a flechette-based rifle for soldiers, but it never performed well […]
Kinetic energy is the extra energy an object has when in motion, described as the amount of work required to accelerate it from rest to its current speed. The equation for non-rotating objects is KE = 1/2 * m * v², where KE is directly proportional to speed squared. Kinetic energy can be more complex […]
Kinetic theory explains the properties of gases in terms of molecular composition and activity. It assumes that gases are made up of small particles that are constantly moving, and that pressure is the result of collisions between molecules. The theory defines pressure as the force exerted by gas molecules when they collide with the container […]
The coefficient of kinetic friction is a unitless variable used to calculate the force of sliding friction in classical mechanics. It depends on material properties and the normal force on an object. The force of friction is independent of an object’s speed or size and is derived from empirical experiments. The coefficient of kinetic friction […]
