Newton`s Laws of Motion – First Law
What is Newton’s First Law of Motion? Newton’s first law of motion states that a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it. Putting Newton’s 1st law of motion in simple words, a body will not start moving until and unless…

Ampere`s Law
What is Ampere’s Law? According to Ampere’s law, magnetic fields are related to the electric current produced in them. The law specifies the magnetic field that is associated with a given current or vice-versa, provided that the electric field doesn’t change with time. Ampere’s Law can be stated as: “The magnetic field created by an…

Coulomb`s Law
What is Coulomb’s Law? According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges. coulomb’s Law Formula In…
