Before we dive into the derivation of Kepler’s Third Law from Newton’s Law of gravitation, we have to first understand what each of these laws means. First off,...

One can think of angular velocity as just the angular version of regular linear velocity: i.e. if linear velocity is defined as the rate of change of displaceme...

The ‘centre of gravity’ is a point through which the entire weight of an object seems to act through. I say ‘seem to’ because in reality, the object’s weight wo...

From the name itself, you can guess an important feature of the variable resistor: it’s resistance can vary. So with every new value of resistance, the amount o...

Before we go into the actual solution, let us first understand what the critical angle is. It is defined as the angle of incidence within the denser optic mediu...

A transverse wave is defined as a type of progressive wave wherein the particles of a medium oscillate in a direction perpendicular to the direction of wave pro...

Let us first define density as the amount of mass contained per unit volume of an object. It is technically a ratio, and is calculated using the formula:So it i...

Faraday’s Law of electromagnetic induction states that the emf induced in a conductor is directly proportional to the rate of change of magnetic flux. Quantitat...

A: This question perhaps encapsulates the wonder of Newtonian Mechanics in the most practical way! For this, let us immerse ourselves in this thought experiment...

Because we’re interested in seeing how the skydiver’s speed is changing with time, a velocity-time graph will be most relevant to us: not only does it have all...
