Chapter 1, Motion and Laws of Motion, introduces the fundamental concepts of how objects move. Motion is the change in position of an object over time and can be categorized into types like rectilinear, circular, and periodic motion. The chapter differentiates between distance, the total path traveled, and displacement, the shortest distance between the starting and ending points in a specific direction. It explains speed as the rate at which an object moves and velocity as speed in a specific direction. Acceleration is discussed as the rate of change of velocity. The chapter also covers Newton’s Laws of Motion, which describe how forces affect the movement of objects. The First Law (inertia) states that an object remains in its state of rest or uniform motion unless acted upon by an external force, the Second Law explains that force equals mass times acceleration (F = ma), and the Third Law emphasizes that every action has an equal and opposite reaction. The chapter concludes with the equations of motion, which are tools used to solve problems related to speed, velocity, and acceleration.
