Work is something that somebody does either consciously or unconsciously, and is either an external job or an inner job. An external job is just any job that an employer pays you to do. An example of external work is someone getting plumbing done in their home. With the explosion of work and home outsourcing, this is a more common occurrence than it was even a few years ago. There are also some jobs that are not external such as driving for a living or being a teacher.
There are different types of work that people do and they can be categorized as being external or internal. External work usually involves someone working outside the premises of their home, while internal work involves working inside the home. External work normally involves some kind of physical contact with the outside world, like driving or carrying materials to work. The main difference between external and internal work is just the proximity, though there are other differences as well, for example what type of work needs to be carried out. External work can often be carried out at the same time every day, while internal work can’t.
The main difference between external and internal work is how much work needs to be carried out. External work would involve anything that needed to be moved, like carrying materials to work, or actually moving things from one place to another. This includes things like lifting heavy objects. Internal work would include things like making calculations or designing plans for something.
A good example of internal work would be a teacher, who has to calculate how many times a student has been dropped by a parent or teacher and then get back up to go to the next lesson. For this teacher, the amount of work involved is almost irrelevant as long as there is some level ground to make it on. For example, if a teacher drops a student then moves a few feet then the speed at which the drop slows down would be exactly what the constant velocity law describes as the friction between the two items.
Therefore, we now know that it is impossible to have zero velocity, even at a low constant speed. And so the Law of Conservation of Energy says that there cannot be a perfect energy, and that friction always occurs. But how can we prove this? Well, since there are no points at which no energy can exist, and so the Law of Conservation of Energy must therefore be accepted, the only possible solution is for the energy level to be zero. Since the velocity of anything increases or decreases with the square of the distance, this implies that you cannot have a perfect energy.
So when we talk about friction and joules we should remember that they are defined as the amount of force required to move an object from a point A to point B. The force required is inversely proportional to the square of the distance, and the force can be defined as a force when you push the object or pull it. Now we have a general idea about how the force on an object depends on its mass, its momentum, and its direction of motion – but how do these quantities change when you are working with electricity, or when you are using a DC motor? In simple terms, you cannot have zero energy, and you cannot have zero velocity, unless you don’t know what zero means! So we can conclude that joules are real, and that they are produced by the friction force between two objects, and not by the total energy of the system.
