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. If an object moves from one position to another we say it experiences a displacement.
(B) describe and analyze motion in one dimension using equations with the concepts of distance, displacement, speed, average velocity, instantaneous velocity, and acceleration; (F) identify and describe motion relative to different frames of reference.
It refers to the numerical measurement of how far an object is from a particular place. Also, in physics, it may refer to the physical length or evaluation based on some criteria. Furthermore, a distance from X to Y is exchangeable with distance from Y to X.
useful formulas and equations found in undergraduate physics courses, covering mathematics, dynamics and mechanics, quantum physics, thermodynamics, solid state physics, electromag- netism, optics, and astrophysics.
Section 3.12 The Distance Formula. If you want to find the distance between two objects in the real world, you measure the distance with a ruler (unless you are an astrophysicist and the distances are too large or you are a particle physicist and the distances are too small!).
