Introduction to Newton’s Law of Universal Gravitation Sir Isaac Newton has done remarkable work in physics, giving a profound theory of gravitation. It associates the gravitational force with masses of two objects and their separation. According to this law, a … Read more
Introduction to Gravitational Force There are four universal forces in nature. Among those forces gravitational force is considered to be the weakest one but has significant effects when the topic is about large-scale structures. It exists between any two objects … Read more
Introduction to Gravitation Gravitation is another type of force acting on two bodies which might have the least impact on the bodies with smaller mass and larger separation between them. However, it turns out to be the strongest one when … Read more
Introduction to Newton’s Laws of Motion Newton’s Laws of Motion are the concepts of Sir Isaac Newton formulated in the 17th century. It consists of three basic laws which describe different forces that act on a body. Thus, the body … Read more
What is a Hysteresis Curve? The word ‘hysteresis’ simply means lagging. In electromagnetism, it is a very useful analysis which suggests the lag of magnetic flux density (B), when magnetic field strength (H) is applied. It is observed that the … Read more
What is the Biot-Savart Law? The Biot-Savart Law is a principle in electromagnetism that deals with the quantitative and qualitative nature of magnetic fields produced by a steady electric current. Hence it provides an empirical relationship between the electric current … Read more
Introduction to Faraday’s Laws of Electromagnetic Induction Faraday’s law of electromagnetic induction or simply known as Faraday law, is an explanation of the direction of electric and magnetic fields. It describes the behavior of the magnetic field when it interacts … Read more
What are Gravitational Waves? Gravitational waves come from the general theory of relativity. They propagate the solution of Einstein’s field equations that describe gravity. Einstein predicted this wave 100 years ago, and it was first discovered on September 14, 2015. … Read more
What is a Transistor? A transistor is a three-terminal semiconductor device used to amplify or switch electrical signals and power. It is one of the most essential tools in electronics. The power provided to one terminal is regulated by the … Read more
