Science > Mathematics > Statistics and Probability > Probability > Concept of Probability First attempt to measure probability was done by Italian mathematician Galileo. The classical theory of probability is developed by French mathematicians B. Pascal and P. Fermat while solving a number of problems posed by a French nobleman and gambler Chevalier-de-mere. The famous […]
Science > Physics > Force > Simple Numerical Problems on Force In this article, we shall study to solve numerical problems to calculate the magnitude of force, momentum, and change in momentum. Example – 01: The speed of a tortoise and hare are 1 m/s and 3 m/s respectively. The mass of the hare is 5 […]
Science > Physics > Force > Concept of Balanced and Unbalanced Forces In this article, we shall discuss the concept of balanced forces and unbalanced forces. Kinematics: The branch of physics (mechanics) which deals with the motion of the bodies without considering the forces causing it is called kinematics. Dynamics: The branch of physics (mechanics) which deals […]
