## 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…

## 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…

## 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…

## How are the base unit and derived units related?

Do you ever wonder how tall Mount Everest is? Or how far is San Francisco from New Delhi? Well, Mount Everest is 8,849 meters tall, and San Francisco is 12,349 kilometers away from New Delhi. But to derive a precise…

## How is coulomb’s law similar to newton’s law of gravitation? How is it different?

If you have learned about both Coulomb’s law of electrostatics and Newton’s law of gravitation while studying mechanics you might be making a comparison about both of them as their formula looks somewhat similar in its form. In this article, we…

## CFM (Cubic Feet per Minutes) unit and its practical application

CFM? You must have noticed this term mentioned frequently in the HVAC industry (heating, ventilation, and air conditioning). The term CFM is an abbreviation for Cubic Feet per Minutes. It is a volumetric flow unit that defines the volume of…

## Why is Volume Measured by a Derived Unit?

Space occupied by an object is called volume and is equal to length times width times height. Since volume depends on measurement of length, width and height, units of volume are measured by a derived unit with units of length…

## What is the unit of measurement for light in photography?

Light Measurement in Photography Light plays a very important role in photography. It is an enhancement that anyone can optimize setting the site of photography properly or sometimes with additional equipment. Overall, it is not just about bright or dark…
