A particle is said to move with variable acceleration if its velocity changes by unequal amounts in equal intervals of time. When a particle moves with variable acceleration, then its average acceleration measured for different time intervals is not the same...

random variables which can assume any value over an interval..

If the change in velocity in equal intervals of time is not the same, then the object is said to be moving with variable acceleratio..

Let X be continuous random variable which can assume values in the interval [a,b]. A function f(x) on [a,b] is called the probability density function if ..

A continuous variable can assume all values within a certain range, e.g., height, weight and age of persons are examples of continuous variables..

Angle, specific gravity, strain etc., do not have any dimensions and any constant value and hence, are variables..

Consider an example: The number of pupils in a class can be 30, 34, 40. But it cannot be 30.2, 35.1, because number of pupils can be expressed only as a whole number. Such numerical as number of children, trees, sheep are called discrete variables..

Example: A rubber ball dropped from a certain height (h 1 ) on reaching the ground bounces up to a height less than the initial one (h 2 ). It continues to bounce but the height to which it rises keeps decreasing (h 3 , h 4 ). The distance covered by the ball in unit time decreases. The speed of t..
