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 theory example, in the case of Proust's tin oxides, one tin atom will combine with either one or two oxygen atoms to form either the first or the second oxide of tin. Dalton believed atomic theory could explain why water absorbed different gases in different proportions - for example, he found that water absorbed carbon dioxide far better than it absorbed nitrogen. Dalton hypothesized this was due to the differences in mass and complexity of the gases' respective particles. Indeed, carbon dioxide molecules (CO) are heavier and larger than nitrogen molecules (N). Dalton proposed that each chemical element is composed of
