What is energy? What is work? List some examples of each.

There are basically two types of energy. We classify energy as heat or work. So when asked, what is the relationship between energy and work? Well, work is one kind of energy. Both energy and work have the same units. Typically, we express them as jewels, and of course it is energy that makes work possible.

Related to energy will work is simply we can say mechanical energy and work is often referred to as mechanical work on. And what this means is that it's simply motion. So we know that the formula for work would be the force. Uh, time the force dr dot product with the displacement factor. Or we can say the magnitude of the force Specter multiplied by the magnitude of the distance Vector times co sign of Fada Fada being the angle between the force vector and the displacement. Dr. So essentially, uh, what does this give you? Well, this gives you Jules, so we know that work is in units of jewels, and we know that energy is also measured in jewels. And so we can say that, um, work would simply be energy that is useful in the sense that it can move something. So it actually it's very dependent on movement. And how is it related? Well, they have the same units. They're essentially work is simply a type of energy mechanical energy again it being, um, dependent on the magnitude of the force and the magnitude of the displacement again. Displacement. If there's isn't any displacement than There is no work actually being done s So that is how work is related to energy. That is the end of the solution. Thank you for watching.

So here work, Um, is the dot product, uh, the force and the distance or the displacement back tears. And then we can say that the dot product actually accounts for the direction. And what the doc product is essentially saying is that the work is the product of the force in the displacement vectors. Or if we were to say, we can say that the doctor, the work is the product of the force and the distance, uh, which an object is moved in the direction of that force. So if it's not moving in the direction of the force that is acting on the object, even if it's still moving, no work is being done on the on the on the mask. And so, of course, power P ah, uh, is the time rate at which work eyes being performed? That is the end of the solution. Thank you for watching
