The theorem determines the moment of inertia of a rigid body about any given axis, given that moment of inertia about the parallel axis through the centre of mass of an object and the perpendicular distance between the axes. The moment of inertia of a body about an axis is equal to its moment of Read more about Parallel Axis Theorem[…]

The locus of the point of intersection of the tangents which are at right angles is known as the director circle of the hyperbola. . The equation to the director circle is x² + y² = a² – b².Example: Hyperbola 9x² – 16y² = 144 then find the equation of the director circle. Solution: The Read more about Director Circle of the Hyperbola[…]
Friction is a force that tries to oppose motion between the two surfaces in placed contact. When we throw a ball on the floor it starting with some velocity. But once it is rolled ideally no force is acting in the direction of motion and according to Newton’s first law the ball should keep on Read more about Friction[…]
Auxiliary circle of an ellipse which is a circle described on the major axis of an ellipse as its diameter. Let the ellipse be … (1)Then the equation of its auxiliary circle is x² + y² = a² … (2) Take a point P(x₁, y₁) on (1). Through P, draw a line perpendicular to major axis intersecting major axis in N and auxiliary Read more about Auxiliary Circle of an Ellipse […]
One of the fundamental conservation laws of physics is the law of conservation of angular momentum which states that the total angular momentum of a system is constant in both magnitude and direction, if the resultant external torque acting on the system is zero. During skating, if the skater folds his or her hands then Read more about Conservation of Angular Momentum[…]

A rectangular hyperbola is also known as an equilateral hyperbola. The asymptotes of rectangular hyperbola are y = ± x. If the axes of the hyperbola are rotated by an angle of -π/4 about the same origin, then the equation of their rectangular hyperbola x² – y² = a² is reduced to or xy = c². 1) A hyperbola whose asymptotes include a right angle Read more about Rectangular Hyperbola[…]
When the mechanical properties of the system do not change then the system is in isolated state and it is called an isolated system. These systems are not interacting with environment and also called system with constant motion. The conservation laws are for isolated system because their properties are conserved and do not change. These laws Read more about Conservation of Momentum[…]
