Calculus For Physics Differentiation Function:                           If the value of a variable quantity (y) depends on another variable quantity (x) through some relation, such that there exists only one finite value of y for each value of x then ‘y’ is called a … Read more

Dimensions                The dimensions of a derived quantity are defined as the powers which are raised on the units of fundamental quantities to represent the unit of the derived quantity, are known as the dimensions of that physical quantity. When the dimensions of a physical quantity are expressed along with the fundamental quantities on … Read more

ACCURACY and PRECISION ACCURACY:  “The extent upto which an observed value agrees with the true value of a quantity is known as accuracy”. Lesser the difference between the true value and the measured value (i.e. lesser the error), more is the accuracy in the measurement. So, accuracy is inversely related to the error involved in … Read more
