INTRODUCTION Motion is one of the significant topics in physics. Everything in the universe moves. It might only be a small amount of movement and very, very slow, but movement does happen. Even if you appear to be standing still, the Earth is moving around the sun, and the sun is moving around our galaxy. “An object is said to be in motion if its position changes with time”. The concept of motion is a relative one, and a body that may be in motion relative to one reference system may be at rest relative to another. There are two branches of physics that examine the motion of an object. (i) Kinematics: It describes the motion of obj...
