## 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

## Radical Physics Intro – God’s Thoughts & the Awesome Machinery of Nature (RP1)

What ho! My name is Tucker Hiatt. I am a physics teacher with 35 years of experience, and I am also the executive director of Wonderfest, the San Francisco Bay Area Beacon of Science. Welcome to Radical Physics. What’s radical — besides our location here in the Gamma Sector of the Milky Way — I’ll

## Introduction to Motion | Physics

Hello there! Now we’ll start the topic kinematics. So in kinematics what we’ll basically study is the ways to define motion. So the basic modules that we’ll be studying here in the next few topics is mechanics. So mechanics is divided into two main categories. The first one is the kinematics which we’ll start now.

## Kinetic Energy | Physics

Energy is available on earth in different forms. These forms are like kinetic energy, potential energy, electrical energy, heat energy etc. We know that a moving object can do work. An object which is moving faster does more work than an object moving relatively slow. Moving bullet, blowing wind, rotating wheel, a speeding stone all

## Inertia, Mass, & a Bad Law of Physics – Newton’s First Law Clarified (RP3)

When asked to cite a very basic law of physics, many people reply with something that they might call “the law of inertia”: An object at rest tends to stay at rest; and an object in motion tends to stay in motion. This would-be law of physics suffers from some BIG problems: Its first half

## How to Tell Matter From Antimatter | CP Violation & The Ozma Problem

Most everyday phenomena happen equivalently in a mirror as they do normally – at least, from a physics perspective. Unlike when you play a video backwards in time (where it’s pretty obvious that something weird is going on), when compared with a normal video, motion in a mirrored video still looks totally physically normal –

## Seismograph | Physics

We know earthquake is a natural phenomena and it can be distructor. But can we measure the intensity of an earthquake? Yes! We can measure the intensity of the earthquake by using an instrument called seismograph. When shaking occurs in the earth crust it produces waves on the surface of earth, these waves are called

## Hear Gil Tell You What He Loves About Science

Gil Toombes and I’m a researcher in Kevin Schwartz’s lab at the NIH. I grew up in Brisbane, Australia and when I was at school I made a promise to my mother that I’d study at university in Brisbane. So afterwards I wanted to go as far away as possible so I came to Cornell
