Gravitation

Introduction The universal law of gravitation was put forth by Sir Isaac Newton in 1687. The inspiration to develop the law came to Isaac Newton after he saw an apple fall from a tree. This article will discuss the weight and the gravitational force, universality of gravity, and gravitational constant. The universal law of gravitation […]

The word gravity has its origin in the Latin word “gravitas”. Moreover, “gravis” means “heavy” and dates back to the 15th century. At the same time, “gravitas” is defined as the weight whose invention dates back to the 17th century.  Aristotle said there is motion in the universe without a cause. He states that the

The pressure within Earth’s atmosphere is known as atmospheric pressure, or barometric pressure (after the barometer). The atm unit roughly corresponds to the Earth’s mean sea-level atmospheric pressure; that is, the atmospheric pressure at sea level is approximately 1 atm. In most cases, the hydrostatic pressure induced by the weight of air above the measuring

A system of particles is described as a group of inter-related particles. Ideally, a rigid body comprises a system of particles with a well-defined shape. A rigid body or object has a perfect or close to a perfect shape. It also means that the object’s shape, size, or other physical features do not change in

Sir George G. Stokes first introduced the Stokes’ law in 1851. Stokes’ law calculates the drag force experienced by a spherical object in a fluid medium. Now, drag force is the frictional force felt by an object which lies in a fluid medium due to the movement of the liquid medium. The law further evaluates

When describing gravitational force, the terms G and g are commonly utilized. Despite the fact that the acceleration due to gravity is tiny g, the universal gravitational constant is large G. Any object’s acceleration owing to gravity is represented by a small g. The universal gravitational constant is known as big G. It has a constant

Many problems can be solved if the mass of the object is believed to be situated in a single location. When the proper position is determined, equations of forces and motion work the same way as when mass is spread out. The centre of mass is the term for this unique site. Its location is

Many problems can be solved if the mass of the object is believed to be situated in a single location. The Centre of Mass is the name given to this unique site. Its location is determined by an object or a group of objects whose Centre of Mass must be computed. It’s usually the centroid

The net gravitational force acting upon an object due to other elements is the vector sum of forces exerted by individual masses on a specific particle, as per the superposition principle of gravitational forces. The superposition principle of superposition property states that the net reaction caused by multiple stimuli is the sum of responses resulting

Pressure Due to a Fluid Column  Pressure can be defined as the perpendicular weight on the surface of an object divided per unit area over which the force is distributed. Pressure is denoted with the symbol  P. In the case of pressure due to a fluid column; as the depth of the fluid increases, so
