Balanced Forces Force can be defined as that pull or push which produces or tends to produce, destroys or tends to destroy motion in a body, increases or decreases the speed of the body or changes its direction of motion.  We apply force or force is applied to us in almost every aspect of our Read more about Balanced Forces[…]

Modulus of Rigidity The modulus of rigidity is also known as shear modulus. It is the material property with a value equal to the shear stress divided by the shear strain. It can be used to explain how a material resists transverse deformation but this is practical for small deformations only. What is Modulus of Read more about Modulus of Rigidity[…]

Rolling Friction Whenever the surface of an object slides over another, each object experiences a contact force. Which always opposes the relative motion between the surfaces, this contact force is called as frictional force. This force acts tangentially to the interface of two bodies. What is Rolling Friction? For a moving solid body, there are Read more about Rolling Friction[…]

Equipotential Surfaces The electric field can be characterised by using the vector quantity, electric intensity and also by using the scalar quantity, the potential. By using electric potential and potential energy, instead of electric intensity and electric force, many difficulties arising due to vector nature of electric field can be avoided. The flow of charge Read more about Equipotential Surfaces[…]
