Motion (physics) an object moves with a constant speed at a particular direction at regular intervals of time it's known as the "uniform motion." For example: a bike moving in a straight line with a constant speed. EQUATIONS OF UNIFORM MOTION: If v = final velocity, u = initial velocity, a = acceleration, t = time, s = displacement, then : Quantum mechanics is a set of principles describing physical reality at the atomic level of matter (molecules and atoms) and the subatomic particles (electrons, protons, neutrons, and even smaller elementary particles such as quarks). These descriptions include the simultaneous wave-like and
Metastability preferred ground state by (possibly large) barriers in the potential energy. During a metastable state of finite lifetime, all state-describing parameters reach and hold stationary values. In isolation: The metastability concept originated in the physics of first-order phase transitions. It then acquired new meaning in the study of aggregated subatomic particles (in atomic nuclei or in atoms) or in molecules, macromolecules or clusters of atoms and molecules. Later, it was borrowed for the study of decision-making and information transmission systems. Many complex natural and man-made systems can demonstrate metastability. Non-equilibrium thermodynamics is a branch of physics that studies the dynamics
