Chapter 2: Motion in One Dimension (Kinematics)
This chapter is where our journey into motion begins! We will focus on the simplest case: an object moving along a straight line (e.g., a car on a road or a falling object).
The key concepts we will explore are:
-
Position, Displacement, and Distance: Understanding the difference between where an object is and how far it has actually moved.
-
Velocity and Speed: Defining how fast an object's position is changing, and distinguishing between velocity (with direction) and speed.
-
Acceleration: Analyzing how an object's velocity changes over time.
In short, this chapter provides the essential vocabulary and mathematical tools to describe motion without yet asking what causes it. Mastering these definitions is the first step toward predicting how objects will move.
