6. Class 11th Physics | Constrained Motion | Simple Pulley Constrained Motion | by Ashish Arora

Now we’ll study simple pulley block constrained relations. you can simply say in pulley systems. these are developed. By analysing. Loosing and. tightening. of strings . due to . motion of blocks . so just be careful about , a pulley block system like, if we just talk about the simplest system which we can […]

Torque: Crash Course Physics #12

You have a box. A ring. And a marble. And they’re all at the top of a ramp. Because you know how physics loves ramps. Especially hypothetical ramps! So, let’s say this ramp would allow for static friction, but not kinetic friction. Now, you let go of all of these objects at the same time, […]

Electric Fields: Crash Course Physics #26

Last time, we talked about how charged particles exert electrostatic forces on one another. We calculated these forces using the charge of each particle: which can be either positive or negative, and the distance between them, and we did it with the help of Coulomb’s Law: the equation that tells us the force generated by […]

Insulin should be cheap. Here’s why it’s not.

– I have type one diabetes. My body doesn’t process glucose properly, which it needs to power muscle tissue and other pretty critical things, like my brain. What I don’t have is insulin. A hormone secreted by the pancreas that helps cells take up glucose in the blood. That means for the past 15 years, […]

Feynman’s Lectures on Physics – The Law of Gravitation

Feynman’s Lectures on Physics – The Law of Gravitation

Ladies and gentleman, it’s my privilege to introduce the Messenger lecturer, Professor Richard P. Feynman of the California Institute of Technology. Professor Feynman is a distinguished theoretical physicist, and he’s done much to bring order out of the confusion which has marked much of the spectacular development in physics during the postwar period. Among his […]

How quantum physics can make encryption stronger | Vikram Sharma

Recently, we’ve seen the effects of cyber attacks on the business world. Data breaches at companies like JP Morgan, Yahoo, Home Depot and Target have caused losses of hundreds of millions and in some cases, billions of dollars. It wouldn’t take many large attacks to ravage the world economy. And the public sector has not […]

So Close and Such a Stranger: a documentary about Condensed Matter Physics

One of whom is Richard Feynmann He said… He was asked: if one piece of knowledge was to be passed to the next generation and everything will be lost, everything we know will disappear, which kind… Which message would you pass to other generations? And he said: that matter is made from atoms. You name […]

The Real Physics of Roller Coaster Loops

The Real Physics of Roller Coaster Loops

If you flip through the pages of just about any physics textbook, you will probably find a picture of a roller coaster loop illustrating the concept of centripetal acceleration. Textbook problems often portray loops that are perfectly circular in order to simplify calculations, but in reality, roller coaster loops are not circular at all. The […]
