Step-by-step guides to mastering motion, waves, and electromagnetism
Learn concepts and formulas to solve kinematics problems quickly and accurately.
Kinematics describes the motion of objects without considering the causes. Use equations of motion like v = u + at and s = ut + ½at² to solve problems efficiently.
Example: Calculate the distance covered by an object accelerating at 2 m/s² after 5 seconds starting from rest.
Explore wave types, properties, and formulas essential for JEE and competitive exams.
Waves transfer energy without transferring matter. Understand wavelength, frequency, amplitude, and wave speed relationships to solve diverse problems.
Example: Find the frequency of a wave traveling at 340 m/s with a wavelength of 2 m.
Simplify electromagnetism topics including electric fields, magnetic fields, and circuits.
Understand Coulomb’s law, magnetic force, and circuit laws like Ohm's law. Knowing vector nature of fields and right-hand rules helps in problem solving.
Example: Calculate the electric field at a point due to two charges placed at given distances.
