Motion refers to the change in position of an object over time. It is a fundamental concept in physics that describes how objects move, whether they are rolling, sliding, or flying. The study of motion involves understanding various factors such as speed, velocity, and acceleration, which help us quantify how fast and in what direction an object is moving. In everyday life, we observe motion all around us, from a car driving down the street to a bird flying in the sky. Understanding motion is crucial for various fields, including engineering, sports, and even space exploration, as it helps us predict and analyze the behavior of moving objects.
