Pascal’s law states that “Pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel”. A small force (F 1 ) is applied to a piston with a small area (A 1 ), resulting a much larger force F 2  …

Newton, along with his three laws of motion, published the law of gravitation in 1687.  According to Sir Isaac Newton, “Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the…

In physics,   energy   is defined as a property of objects that can be transferred from one object to another or converted into different forms of energy. Energy is the capacity to do work, generating heat and emitting light. Heat is the ability to change an object&#…

Comparison of solids, liquids and gases (fluids) can be done in aspects like macroscopic description, mobility of molecules, density, molecular spacing, effect of shear stress, effect of normal stress, viscosity and compressibility is represented below in tabular form…

Kepler's First Law (The Law of Ellipses): Each planet moves in an elliptical orbit, with the sun at one focus of the ellipse. This law is also known as the law of elliptical orbits and obviously gives the shape of the orbits of the planets around the sun. Kepler…

The problems of mechanics can be solved by Newton's laws of motion . The three laws proposed by Sir Isaac Newton are described as follows. Newton's First Law of Motion: Newton's first law of motion states that every object will remain at rest or in un…

Comparison of solids, liquids and gases (fluids) can be made in aspects like macroscopic description, mobility of molecules, density, molecular spacing, the effect of shear stress, everyday stress, viscosity and compressibility below in the tabular form. S.No A…

Energy cannot be created or destroyed but can only change from one form to another. The law of conservation of energy  does not distinguish between valid and wasted  energy . The law neglects ‘losses’ from the closed system into the environment. In an energy conservati…
