Welcome to the fascinating world of Physics where we delve into the intricate relationship between matter, space, and time. In this course material, we will embark on a journey to understand the fundamental concepts of 'Position, Distance, and Displacement'.
Understanding the Concept of Position in Space: To begin our exploration, we will grasp the concept of position in space using the X, Y, and Z axes. By visualizing these axes, we can precisely locate objects in three-dimensional space. The position of an object can be uniquely identified through its coordinates on these axes, providing a comprehensive understanding of its spatial orientation.
Differentiating Between Distance and Displacement: A crucial aspect of our study involves distinguishing between distance and displacement. While distance refers to the total length of the path traveled by an object, displacement signifies the change in position from the initial point to the final point. Through thought-provoking examples and practical applications, we will delve into the intricacies of these concepts.
Accurate Measurement of Distance: Measurement plays a pivotal role in Physics, and we will learn to measure distance with utmost precision. By utilizing instruments such as the metre rule, vernier calipers, and micrometer screw gauge, we can determine distances with varying degrees of accuracy. Emphasizing the use of the metre as the unit of distance, we will hone our measurement skills to obtain reliable and precise results.
Demonstrating Directional Concepts: Direction is a key component in spatial analysis, and we will explore the concept of direction as a means of locating a point. Through the use of a compass and protractor, we will learn to determine bearings and interpret directions accurately. Graphical representations will aid in visualizing locations and orientations by axes, enhancing our directional comprehension.
Utilizing Rectangular Coordinates: For positioning objects with accuracy, we will employ rectangular coordinates as a reference system. By specifying coordinates along the X, Y, and Z axes, we can precisely locate objects in space. This methodical approach enhances our spatial visualization skills and enables us to navigate the complexities of positioning in a three-dimensional realm.
As we delve deeper into the intricacies of 'Position, Distance, and Displacement', we will unravel the mysteries of spatial relationships and equip ourselves with the tools to navigate the dynamic world of Physics.

You are provided with a loaded boiling tube with a centimeter scale fixed inside it, a transparent vessel filled with water, standard masses 2 g, 5g and 10 g, and a slide vernier caliper. Use the diagram above as a guide to perform the experiment.
(i) Use the slide vernier caliper to measure and record the external diameter, D, of the boiling tube.
(ii) Evaluated A = 0.25?D2, where ? = 3.14.
(iii) Place the loaded boiling tube gently in the water in the transparent vessel such that it floats vertically.
(iv) Read and record the depth of immersion, y, from the zero mark of the scale fixed inside, the boiling tube.
(v) Add a mass, m = 2g, to the boiling tube. Read and record the new depth of immersion, y, from the zero mark of the scale.
(vi) Evaluate h = (y - y0), log h and log m.
(vii) Repeat the experiment for four other values of m = 5g, 7g, 10 g, and 12g. In each case, record y and evaluate h, log h, and log m.
(viii) Tabulate the results.
(ix) Plot a graph with log m on the vertical axis and log h on the horizontal axis starting both axes from the origin (0,0).
(b)(i) State in full the law on which the experiment in (a) is based.
(ii) A uniform cylindrical rod is 0.63 m long and it has a cross-sectional area of 0.1 m2. Calculate the depth of immersion of the rod if it floats vertically in a liquid of relative density 1.26. [density of rod =720 kg m?3, g = 10 m s?2].
