Gravitation

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 […]

In our day-to-day lives, we often interchange the terms weight and mass. However, in physics, there is an important distinction between the two. Weight is the pull of the Earth on a specified object. It depends on the distance from the centre of the Earth. However, the mass of an object does not vary with

Gravity is an enormous force in nature which is present in macro objects like planets, stars and galaxies to micro-objects like atoms, molecules etc. It is the attraction force present between the objects. Whenever there exist two objects with mass, the gravitational constant can be used to determine the force between them. The Gravitational constant

The dimensional formula of any bodily amount can be defined as the expression representing the specific bottom portions protected in that amount. It is given by mentioning the symbols for base portions with suitable strength in rectangular brackets, i.e. []. An example is the Dimension Formula of Mass which is given as [M].  Acceleration due

Stress Stress is defined as the force applied to a material divided by the cross-sectional area of the substance. stress force initial cross-sectional area Strain Strain is the material’s deformation or displacement as a result of applied stress. strain new length  initial length Young’s modulus Young’s modulus is a numerical constant named after Thomas Young,

The centre of mass is the unique spot where the entire mass of an object or system of particles is concentrated. It is the point where the force applied results in linear acceleration without an angular acceleration.  The centre of mass of objects varies. For a single rigid body, it is fixed in relation to

The Latin (or Greek) words “centrum” and ” gravitation ” are the origins of the word “centrum” and ” gravitation.” Gravity is the weight, or attractive force, between particles in the cosmos that causes celestial bodies to move, and the centre (centroid) is the centre of mass in the middle of the body’s diagonals. Centre

Ever tried to make a pencil stand on your fingertip and succeeded? Or balanced rocks one over the other, carefully placing them so that your rock-tower does not collapse? These are the perfect examples of instances where the centre of gravity comes into play. The centre of gravity of any object is an imaginary centre

The central force is a radial force whose magnitude is proportional to the distance from the source. The gravitational force, electrostatic force, and spring force are examples of core forces. In classical mechanics, the central force is defined as the force exerted on an object that concentrates along the line between the object and the

Introduction Water molecules need to hang differently. This consequence is a more potent bond than the molecular bonds that are in touch with one another and form a layer of strongly bonded water. This surface layer (held collectively via surface tension) creates a widespread barrier between the environment and the water. Apart from mercury, water
