## Do We Really Need a Battery | Physics

Hey friends! Ever wondered, what drives the current in an electrical circuit? What’s the role of a battery we get at the electrical stores. For those of you, who are really fascinated by gadgets, electrical appliances, in this video we find out that do we really need a battery in a circuit. Let’s have a

## Force – a Push or Pull | Physics

Force, a very common word, right? As you can see some images over here, in all the see some images over here, in all the images, people are doing something, right? images people are doing something, right Let’s analyze what exactly are they let’s analyze what exactly are they doing over here? In the first

## Modern Periodic Table | Chemistry

So many attempts of classifying elements had failed. Then in 1913 an english physicist Henry Moseley found out that the fundamental property of an element is not atomic mass but it is it’s atomic number. Because atomic number tells us the number of electrons present in any atom of the element and number of electrons

## Uniform Motion and Non-Uniform Motion | Physics

Motion can be of two types: a uniform motion something like this or a non uniform motion something like this. I’m sorry, we are here to learn about Physics. Uniform motion is when an object travels equal distances in equal amounts of time. Let’s look at this car. You can see that this car is

## Refraction and Refractive Index | Physics

By now, you must have got a good hold on the concepts related to mirrors. the concepts related to mirrors. Want to explore the phenomena related to light mode? Let us see, till now we were dealing with light traveling in air only that is, light traveling in one medium. light traveling in one medium

## Rules to solve Linear Equations | Maths

Ah! why are there always so many rules, don’t run in the corridors, don’t talk too loud, don’t finish all the ice cream in the fridge, I’m fed up. Hey! but I can’t deny the rules do come in handy sometimes, i mean I would definitely fail my linear equations test if I didn’t know
