Various forms of Circle Equation Circle passing through 3 points: 1. Let x² + y² + 2gx + 2fy + c = 0 be circle passing through 3 points (non-collinear) then P (x₁, y₁), Q (x₂, y₂), R (x₃, y₃). x₁² + y₁² + 2gx₁ + 2fy₁ + c = 0 x₂² + y₂² + Read more about Various forms of Circle Equation[…]
Motion of a car on banked road Friction is not always reliable at circular turns if high speeds and sharp turns are involved. To avoid dependence on friction, the roads are banked at the turn so that the outer part of the road is somewhat lifted up as compared to the inner part.The surface of Read more about Motion of a car on banked road[…]

Position, Path length and Displacement Before we learn about Position, Path length and Displacement, let us know what motion is, Earlier we learnt that motion is change in position of an object with time. Everywhere we see objects moving around. Animals go from one place to another in search of food, shelter. River flow, earth Read more about Position, Path length and Displacement[…]
Collinear and Coplanar Vectors Collinear Vectors: They can have equal or unequal magnitudes and their directions may be same or opposite. Two vectors are collinear if they have the same direction or are parallel or anti-parallel. They can be expressed in the form a = k b where a and b are vectors and ‘ k ‘ is a scalar Read more about Collinear and Coplanar Vectors[…]

Simple Harmonic Motion In the preceding sections, the motion of a body when acted upon by a constant force was considered. The motion is one of constant acceleration. In this section, the motion of a body subjected to a variable force is considered. There is one common and important type of non-uniformly accelerated motion that Read more about Simple Harmonic Motion[…]
Condition for Parallel or Perpendicular Lines When the two lines are perpendicular, the angle between the lines is 90° which gives the condition of perpendicularity as l₁ l₂ + m₁ m₂ + n₁ n₂ = 0 or this implies a₁ a₂ + b₁ b₂ + c₁ c₂ = 0. Similarly, when the two lines are parallel, the angle between them i.e. θ = Read more about Condition for Parallel or Perpendicular Lines[…]
