Kinematics: notes and previous year questions

Free notes for every topic in kinematics, with the key formulas and real JEE and NEET questions solved step by step.

Frame of ReferenceWhy rest and motion depend on who is watching, which frames obey Newton's laws as they are, and how pseudo forces handle the rest.
Motion in a Straight LineDistance and displacement, speed and velocity, acceleration and its sign, and how calculus links position, velocity and acceleration.
Kinematic EquationsThe four equations of motion for constant acceleration: where they come from, how to pick one, and how to use them for falling and thrown objects.
Graphical AnalysisReading position–time, velocity–time and acceleration–time graphs: slopes, areas, curvature, signs, and graphs that cannot happen.
Motion in a PlanePosition, velocity and acceleration as vectors, the independence of perpendicular motions, and the split–solve–stitch method.
Projectile MotionAnything thrown and left to gravity: horizontal and oblique throws, time of flight, height and range, the trajectory, and throws from a height or up a slope.
Relative VelocityHow motion looks from something that is itself moving: in a line, in two dimensions, in the rain, across a river and in a wind.
Circular MotionWhy moving round a circle at a steady speed still needs an acceleration, and how angles, angular velocity and centripetal acceleration describe it.
