let’s go back to the definition of work done by a particle of the goes from point P 1 to point P 2 to calculate the work we need to integrate from P 1 to P2 the force times ‘dx’. For simplicity a will work in just one dimension. Inside the integral I can substitute […]

Hey guys, Trace here for DNews. San Francisco is notoriously hilly and when you’re going up and down those hills, you get potential energy and kinetic energy and it gets wasted if you don’t harvest it back from your environment which brings us to something called regenerative braking. Before we get to the science of […]

The kinetic energy of a body is the one that it possesses due to its movement. Equivalent to half the mass times velocity squared. The bottom block has twice mass and therefore twice as much energy than the above; the bottom block moves twice speed than the above then it has four times the kinetic […]

## 13. Class 11th Physics | Work Energy Power | Work-Energy Equation for Rigid Bodies | by Ashish Arora

let us study work energy equation for rigid bodies. as we have already studied . for rigid bodies. we can simply state these can never be deformed, rigid means, these can never be deformed . rigid bodies can contain only ki-netic energy elastic potential energy can never be stored in these. so , independently in […]

Hi. This week’s lab is on exploring the mechanical energy of a volleyball as it gets tossed or bounced. Of course, you know something about the conservation of energy, where the kinetic energy as you throw something up changes into gravitational potential energy and changes back to kinetic on the way down so then you […]

As we venture into the topic of thermochemistry, we first need to lay the groundwork of some basic terminology. As we’ve previously discussed, energy is the capacity to do work and work is a force acting over a distance. We can categorize energy as kinetic or potential energy. Kinetic energy is the energy of motion […]

– Good morning. Today we are going to use calculus to derive the work-energy theorem. And I do understand because this is an algebra-based class that many of you have not taken calculus yet. However, I consider it important to sometimes see math which is a little bit more advanced than what you currently understand. […]

I have here a pendulum. I have an object that weighs 15 kilograms and I can lift it up one metre, which I have done now That makes I have done work. mgh is the work I have done, believe me. I have increased the potential energy of this object, 15 times 10, to 150 […]

We need energy for pretty much everything, from keeping our bodies moving to keeping the sun burning. But where does it come from? And /why/ do we need it? What /is/ energy, anyway? Hey there! My name’s Alie Energy is pretty complicated, but we’re going to figure it out together! Physicists often describe energy as […]

A hydrogen atom has less mass than the combined masses of the proton and the electron that make it up. That’s right, less. How can something weigh less than the sum of its parts? Because of this. And today, we’re going to clarify what the most famous equation in physics really says. [MUSIC PLAYING] E […]
