Young’s modulus, also known as the modulus of elasticity, is a measure of the stiffness of a material. It is defined as the ratio of the stress applied to a material to the strain produced in the material. In other words, it describes how much a material will deform when subjected to a force. The…
The period of a simple pendulum can be used to determine the acceleration due to gravity, g. The formula for the period T of a simple pendulum is: T = 2π√(L/g) where L is the length of the pendulum and g is the acceleration due to gravity. To determine g using a simple pendulum, follow…
Error analysis is an important aspect of any experimental study, as it allows us to understand and quantify the uncertainties associated with the measurements made during an experiment. In the case of experiments based on using Vernier calipers and screw gauge (micrometer), the following sources of error should be considered: To minimize these errors, it…
Methods of measurement refer to the techniques or tools used to quantify or assess a particular attribute or characteristic of an object, organism, or system. The following are some commonly used methods of measurement: What is Required General Methods of measurement The required general methods of measurement depend on the type of attribute or characteristic…
Significant figures, also known as significant digits, are the digits in a number that are considered to be meaningful and relevant. They are used to indicate the precision of a measurement or calculation, and they help to ensure that results are reported with the appropriate level of accuracy. The number of significant figures in a…
Least count is the smallest measurement that can be read and recorded by a measuring instrument. It is a significant term in metrology, which is the science of measurement. The least count of a measuring instrument is determined by its smallest scale division. For example, the least count of a ruler with markings in millimeters…
Dimensional analysis is a mathematical technique used to check the correctness of equations and to convert one unit of measurement to another. It involves analyzing the dimensions of physical quantities involved in a problem and setting up equations based on these dimensions. In dimensional analysis, physical quantities are expressed in terms of fundamental dimensions such…
In physics and engineering, units and dimensions are used to quantify physical quantities. A unit is a standard quantity used to express a physical measurement, while a dimension is a type of physical quantity that can be measured. There are seven base units in the International System of Units (SI) which are: All other units…
