Heat Transfer and modes of heat transfer Heat transfer:- It deals with rate of energy transfer. Energy transfer from one system to another system or from one part of system to another part of system is due to temperature difference is called heat transfer. Basic cause of heat transfer is temperature difference. Heat transfer helps…
Elasticity and Hooke’s law of elasticity What is Elasticity? It is the property of a body by virtue of which body tends to regain its original shape and size after unloading. and the deformation called elastic deformation. for example steel, rubber, concrete and quartz. The Elastic behavior of materials plays an important role in engineering…
Surface Tension, it’s unit and applications Surface Tension:- It is the property of fluid tries to shrink into minimum surface area and enables to resist tensile stress. It is define as the surface Tension force per unit length. Surface Tension= Force/Lengthσ = F/LSI Unit of Surface Tension= N/mMKS unit of Surface Tension= Kg/s2CGS unit of…
Pressure, It’s unit and applications What is Pressure? The Force acting on a unit area of a surface is called pressure. Pressure = Force/Area P=F/ASI unit of pressure : N/m = Pascal = Pa Pressure, It’s unit and applications Pressure is inversely proportional to the area. It means that if area of any body increases…
Work, Energy and Power What is work? When force is applied on any object and object tends to move is called work done. there is displacement of the object or body. it is a scalar quantity The amount of work is equal to the product of applied force and displacement of body in the direction…
Motion and it’s types | Newton’s law of motion Definition of Motion:- Motion :- Change in position of an object with respect to time is called motion. Generally it is classified into to types – Linear motion and non linear motion. Further classification of motion on the basis of uniformity:- Velocity: It is displacement per…
Fundamental Quantities and it’s unit What is Unit? The measurement of any physical quantity with reference of any standard is known as unit. There are Two types of units:- What is Scalars and Vectors quantities? List of Fundamental or base Quantities, it’s SI units and symbols. Fundamental Quantities and it’s unit Base Quantity SI units…
Explain about force and it’s type Definition of Force:- It is an external source which may produce or tends to produce, destroy or tends to destroy the motion of body while acting on a body. SI unit of of force is Newton and the CGS unit of force is dyne. [1N= 105 dyne]. Symbol F…
