## Newton’s First Law | Physics

In this video we are going to learn about Newton’s laws. This is the most important topic in whole of physics. Before we start discussion on Newton’s laws, let me tell you two situations where you cannot apply Newton’s laws. First situation when the speed of objects is an appreciable fraction of the speed of

## Force, Inertia, & Newton’s First Law of Motion (RP4)

Welcome back to Radical Physics. It’s time to learn our first official law of physics. This is exciting: the first law of physics! We might call it the first — and most basic — law of nature. No one knows why this law is true. And it took people a LONG time to realize that

## Work & Power in Physics (RP11)

The concept of WORK is very important in physics, and it’s important — and laborious! — in everyday life, too. But in physics, Work intimately connects to two deep ideas that Radical Physics has already explored: FORCE and ENERGY. You remember, I hope, that FORCE is just a push or pull. We defined it that

## 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

## Types of Force in Physics – Diversity, Meaning, & Measurement (RP5)

RP4 tells us a lot about force, IN GENERAL. Let’s briefly look at a few SPECIFIC forces. Many of these will be considered in detail in later episodes. We are all familiar with the force of gravity. On Earth, gravity gives things weight. It is a force (measured in newtons, as are ALL forces) that

## Unified atomic mass units | Nuclear Physics | meriSTEM

another common way to describe nuclear masses is in terms of the unified atomic mass unit the symbol for this unit is a lowercase letter u as we will see shortly this is a convenient unit because the mass of an atom in atomic mass units is approximately equal to the total number of nucleons
