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
Atomic orbital as a starting point for the calculation of the properties of atoms and molecules with many electrons: Although hydrogen-like orbitals are still used as pedagogical tools, the advent of computers has made STOs preferable for atoms and diatomic molecules since combinations of STOs can replace the nodes in hydrogen-like atomic orbital. Gaussians are typically used in molecules with three or more atoms. Although not as accurate by themselves as STOs, combinations of many Gaussians can attain the accuracy of hydrogen-like orbitals. The term "orbital" was coined by Robert Mulliken in 1932 as an abbreviation for "one-electron orbital wave function". However,
