Introduction to the Feather and Coin Experiment When gravity was not defined, everything was suspected to fall depending on its mass. According to Aristotle, massive objects fall more rapidly than … Read more
Introduction to Free Fall While studying force and motion, we have to deal with acceleration, which is a fundament of force. Again, while studying gravitational force, we talk about gravitational … Read more
Introduction to Acceleration Due to Gravity We have studied that every object falls down to earth when thrown upward. This is certainly because of gravity. These objects also fall at … Read more
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 … 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 … 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. … 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 … 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 … 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. … Read more
