Internal Energy of a Body   Internal Energy of a body is the sum of all kinetic and potential energy of all molecules constituting the body.   if they do not have time to read and work on them. So far, at the moment, when I recommend someone to listen to something, people, as a…

Hooke’s Law of Elasticity in Physics   Introduction:   An English Physicist and Chemist Robert Hook discovered this law in 1678.   Statement “Strain produced is proportional to the stress exerted within the elastic limit.   Elastic Limit: The point at which a material becomes plastic is called elastic limit on yield point.   Yield…

Types of Strain in Physics   Following are some types of strain.   Tensile Strain: It is a change in length divided by original length.   Bulk Strain: It is the change in volume divided by original volume.   Shear Strain: It is equal to the angular displacement produced.   How to explain to fish…

Difference between Stress & Strain   When a body is made to change its length, volume or shape by the application of an external force, the opposing force per unit area is called Stress.     Formula:   Stress = Force / Area o = F/A (Here o represents (Rho) do not write in your…

Strain in Physics   Strain:   Stress can produce a change in shape, volume or length in an object. This change in the shape of an object is called strain.   Formula:   Mathematically,   Strain = Change in Length/Length or Strain = Change in volume / volume   Units:   2 Since strain is…

Different Types of Stress in Physics   Following are some types of stress:   Tensile Stress: It is a stress tending to stretch a body.   Bulk Stress: It is an overall force per unit area, also known as pressure.   Shear Stress: It is a stress tending to produce an angular deformation.   which…

Stress in Physics Terms   When a body is made to change its length, volume or shape by the application of an external force, the opposing force per unit area is called Stress.     Formula:   Stress = Force / Area   o = F/A (Here o represents (Rho) do not write in your…

Elastic Behavior and Molecular Theory   The elastic behaviour of a material can be explained by the Kinetic Theory of Matter. Since the molecules in a solid are very close to each other, there exist strong attracting forces between them. Thus when force is removed, the attraction forces between the molecules pull them back again…

Definition of Elasticity   “The tendency of a material to return to its original dimension after the deforming stress has been removed is known as elasticity.”   If we apply a force to a body, it is stretched. When the applied force is removing, the body returns to its original shape. The phenomenon of turning…

States of Matter in Physics   States of Matter: Matter has been classified into three states. These states are discussed below: 1.5mm.   Solid:   According to the kinetic theory of matter, solid has the least kinetic energy. The properties of solids are given below:   a- The particles are very close to each other.…
