1. Position and Displacement: Position: Location of an object relative to a reference point. Displacement: Change in position; includes direction and magnitude.

Kinematics is the branch of physics that studies the motion of objects without considering the forces causing that motion. It's the science of describing and analyzing the motion of objects, including their position, velocity, and acceleration, without delving into the forces that produce that motion. By focusing solely on the motion itself, kinematics provides a fundamental framework for understanding various physical phenomena, from the motion of planets and stars to the movement of atoms and particles.

Chapter: Units and Measurements Topic: Dimensions and Dimensional Analysis 1. Dimensions of Physical Quantities Dimensions of a physical quantity are the powers to which the fundamental units (base quantities) must be raised to represent that quantity. 1.1 Fundamental Quantities and Their Dimensions
