In mechanics, a variable-mass system is a collection of matter whose mass varies with time. It can be confusing to try to apply Newton's second law of...

law for variable mass systems by treating the mass in F = dP/dt = d(Mv) as a variable. [...] We can use F = dP/dt to analyze variable mass systems only if...

A variable-buoyancy pressure vessel system is a type of rigid buoyancy control device for diving systems that retains a constant volume and varies its...

Beta Lyrae variables are a class of close binary stars. Their total brightness is variable because the two component stars orbit each other, and in this...

distributions of discrete variables can be expressed in terms of probability mass functions. In discrete time dynamics, the variable time is treated as discrete...

In a real spring–mass system, the spring has a non-negligible mass m {\displaystyle m} . Since not all of the spring's length moves at the same velocity...

A variable star is a star whose brightness as seen from Earth (its apparent magnitude) changes systematically with time. This variation may be caused by...

Variable air volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume (CAV) systems, which supply...

LHS 68. It is a variable star showing flares as well as smaller brightness changes due to rotation. The aggregate mass of the system is 0.3262±0.0018...

(FFF) system is a humorous system of units based on unusual or impractical measurements. The length unit of the system is the furlong, the mass unit is...

A random variable (also called random quantity, aleatory variable, or stochastic variable) is a mathematical formalization of a quantity or object which...

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting...

component stars are both flare stars with the variable star designations BL Ceti and UV Ceti. The star system was discovered in 1948 by Willem Jacob Luyten...
