Kirchhoff’s Laws These are used to solve circuits with multiple loops and branches. 🔹 1. Kirchhoff’s Current Law (KCL) At any junction, the sum of currents entering = sum of currents...
Definition: Ray Optics (Geometrical Optics) deals with the study of light in terms of rays and the formation of images by reflection and refraction. It ignores wave nature of light. Focuses...
Definition: Centripetal acceleration is the acceleration of a particle moving in a circle, directed towards the center of the circle. Even if speed is constant, velocity changes because direction...
Kinematics in Physics Kinematics is the branch of physics that studies: Motion of objects without considering the cause of motion (force). So in kinematics, we describe: How fast something...
