Kinematics is the science of describing the motion of objects. Such descriptions can rely upon words, diagrams, graphics, numerical data, and mathematical equations. This chapter of The Physics Classroom Tutorial explores each of these representations of motion using informative graphics, a systematic approach, and an easy-to-understand language.
In this chapter, we study speed, velocity, and acceleration for motion in one-dimension. One dimensional motion is motion along a straight line, like the motion of a glider on an airtrack.
In the following examples, we further explore one-dimensional motion, but in situations requiring slightly more algebraic manipulation. The examples also give insight into problem-solving techniques. The box below provides easy reference to the equations needed.
In this chapter, we examine the simplest type of motion—namely, motion along a straight line, or one-dimensional motion. In Two-Dimensional Kinematics, we apply concepts developed here to study motion along curved paths (two- and three-dimensional motion); for example, that of a car rounding a curve. Previous Next.
28 maj 2024 · Explore the essentials of one-dimensional motion, delving into velocity, acceleration, time, and kinematic equations in this comprehensive guide.
With one-dimensional motion, we can define a straight line along which the object moves. Let’s call this the x-axis, and represent different locations on the x-axis using variables such as and , as in Figure 2.1. Figure 2.1: Positions = +3 m and = –2 m, where the + and – signs indicate the direction.
Highlights. Learning Objectives. By the end of this section, you will be able to: Calculate displacement of an object that is not accelerating, given initial position and velocity. Calculate final velocity of an accelerating object, given initial velocity, acceleration, and time.
