Units and Vectors - Lumos Educational App Store

Understand the importance of fundamental units of physical quantities and distinguish between the two systems of units. Explore the rules for writing the units for any physical quantity. Estimate and measure very small and very large distances. Determine the dimensions of any physical quantity, using dimensional analysis. Understand the nature of errors and methods of analysis of the errors in measurement. Observe and understand the difference between accuracy and precision. Determine the number of significant figures in a numerical value. Analyse the least count of some measuring devices. Differentiate between vectors and scalars and investigate the importance of vectors with relevance to daily life applications. Express vectors in different types of co-ordinate system. Identify the types of vectors and resolve them in to their corresponding components, based on the angle subtended. Employ methods for addition and multiplication of vectors, with reference to the properties of dot and cross products.
