Science > Physics > Newton’s Laws of Motion > Reference Frames Before studying Newton’s laws of motion, we shall understand a very important concept of reference frames in this article. Motion is a Relative Concept: Motion is always with respect to the observer. Consider a person A is standing in a train moving in the […]
Science > Chemistry > Atomic Structure > Problems Based on Atomic Number, Mass Number, and Neutron Number In this article, we shall study to solve problems based on the calculation of atomic number, atomic mass number, and neutron number Atomic number (Z) : The number of protons (positive charge) present in the nucleus of an […]
Science > Physics > Wave Theory of Light >Photometry and Sources of Light In this article, we shall study brief history of study of light, sources of light, andterminology of optics. History of Study of Light: Light is a form of that energy which simulates our vision. Around 400 B.C., it was proposed that particles […]
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 Force When we push, pull, kick, lift, throw, flick, hit, pick, squeeze, press, inflate, open, close an object we say a force is applied on the object. These actions are nothing but the application of force. Whatever may be the method of application of the force, they […]
Science > Physics > Physics and Other Sciences LIST OF SUB-TOPICS Physics is a study of matter and energy in its different forms. In other words, physics is the study of nature and its laws. We expect that all the different events taking place in nature always take place according to some basic rules and […]
Science > Physics > Introduction to Physics List of Sub-Topics: 1.1.1.1 What is Physics? Science word is derived from the Latin word ‘Scientia’ which means ‘to know’. Science has many disciplines, Physics being one of them. The word Physics is derived from the Greek word ‘Fusis’ meaning ‘nature’. Physics is that branch of Science which […]
