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
Comparison of chemistry and physics studies the properties of matter at a larger scale (for example, astrochemistry) and the reactions of matter at a larger scale (for example, technical chemistry), but typically, explanations and predictions are related back to the underlying atomic structure, giving more emphasis on the methods for the identification of molecules and their mechanisms of transformation than any other science. Although both physics and chemistry are concerned with matter and its interaction with energy, the two disciplines differ in approach. In physics, it is typical to abstract from the specific type of matter, and to focus on the common properties of many
