## What is the unit of measurement used for atomic particles?

An atom is the smallest unit that makes up an element, but it is not the smallest or fundamental particle of matter. Atoms itself are made up of various particles like electrons, neutrons and protons. Like larger masses which we study in Newtonian … Read more

## How to find vector components from magnitude and angle

We already know what are vectors in physics and How to represent vectors graphically. In this article, we will look at the way to find vector components from magnitude and angle. Finding vector components from magnitude and angle Let us proceed further with … Read more

## What is required for an electric charge to flow through a wire?

An electrical current is the movement of charged particles, such as electrons and ions, through an electrical conductor. In a conductor electric charges do not start to move on their own. They move inside a conductor only if they are forced to move … Read more
