Universal law of gravitation

Gravity, as well as gravitational force, can be written interchangeably with each other. However, they are not the same thing; they are quite different from one another. Gravity, as well as gravity force, happens between every matter that exists on this planet. It is also considered the weakest force on Earth and plays no part […]

Contact forces are forces that occur when two interacting items are believed to be physically engaging one another. Forces are defined in newtons (N or kgm/s²), while displacements are expressed in metres (m). Despite their great physical separation, the sun and the planets, for example, have a gravitational pull towards one another. There is also

Conservative force is nothing but a force. The force is independent of the path of the particle. It means that the conservative force depends only on the object’s position or the start and endpoints. The conservative force will be zero if a particle moves in a closed loop.  The conservative force law conserves energy. The

Weight, in a practical sense, refers to how heavy or light an object is, regardless of its size or shape. Identifying whether an object is heavy or light is also a simple task. The practical reference of light and heavy, on the other hand, becomes problematic when estimating the actual weight of an object. Also

Introduction We live on the earth, and on it, we can walk and breathe air that does not escape into space. Life on earth is possible because of gravity. Gravity is also the phenomenon that governs all planetary motion in space. Gravity is the attractive property of any given mass. Gravitation does not depend on

Any fluid exists in layered form. The friction between the layers of the fluid causes drag. This drag which affects the motion of the fluid is termed as viscosity. When an object is dropped in a fluid, the viscosity of the fluid affects the motion of the object. During its motion the highest velocity attained

The only thing that would happen if you tried to smash a ball pin into a wall is that people would stop giving you their ball pins. When pounded with the same force, a nail, on the other hand, is considerably more likely to pierce the wall. All of the force between the wall and

Introduction Every object when in linear motion experiences some form of load due to applied force during the motion that acts upon the object. The object that experiences this gives an opposite reaction to the loads, this is described as mechanical properties. For an object that is subjected to any sort of compression or tension

In Physics, forces that describe the deformation of objects are called stress and strain. The force acting per unit area of a body is called stress, whereas the result of stress on a body or the deformation caused by the stress on the material is called strain. Thus there is a direct relationship between stress

Definition of Stress-strain Curve: Generally speaking, angles representing the relationship between stress and strain in any form of distortion can be regarded as stress-strain angles. Stress and strain can be normal, shear, or admixture, also can be uniaxial, biaxial, or multiaxial, indeed change with time. The form of distortion can be contraction, stretching, torsion, gyration,
