In Physics, work is energy transferred from or to an object through the application of force over a certain space without any change in the object’s position or orientation. In its most simple form, it can be symbolized as the product of the force and distance. This is the definition used in all textbooks on Physics and is well understood. However, many students find this definition confusing because they are not taught how to appropriately interpret it when they are solving real-life problems such as working with springs or elastic materials.
The amount of work done on an object will depend on the force that is applied, the distance that is moved from the point of contact, and the direction that the force is applied in. For instance, if we were to calculate the amount of work needed to lift a weight from a table, the first component would be the force that is exerted upon the weight, which is then followed by the distance from where the weight is lifted to the point where it is dropped back to the floor. Another component would be the time taken to move the object from point A to point B, and the final component would be the force that is exerted upon the drop-off point. This is the definition of Physics used in order to solve problems concerning movement.
To solve a problem involving two vectors, the distance between the point A and point B, and the angle between the vectors a and b must be measured in some way. For instance, if we wanted to calculate the amount of work needed to pull the weight off of a table in question, we could begin by finding the tangent to the two vectors, which is the horizontal distance between A and B, and the vertical distance between a and b. From here we could determine the angle between the vectors, which is always positive, and then calculate the resultant force. This would tell us the amount of work needed to accomplish the task. However, one thing that must be remembered is that if the angle between the vectors is zero, then there will be no work whatsoever, and the formula will simply be a formality.
In order to get more in-depth with this concept, consider the next scenario: you have an apple tree at the edge of a cliff, which is falling down. Your classmate Dave is having his apple fall to the ground, while he is still above the tree. What will happen if you make your move at exactly the right time, and swing your table over the edge of the cliff? You guessed it; Dave is going to hit the ground before your apple does! This example illustrates why the term for cosines, or the force that is applied to an object for the same reason that the force would be applied to an object at rest, is called the tangent.
If you are wondering how to find your exact work out of your total body strength, you need to know that all your work done in this class, no matter how small, will be included in your computation of yourergonomics or work space. Yes, the definition of ergonomics is about making life comfortable, and in this case, that takes care of work done by your feet. It doesn’t matter how many new terms and concepts are introduced in this article, a basic knowledge of the meaning of the equation Total Body Energy (TBE) and the formulas associated with it should be sufficient to understand how it works. For the purposes of this lesson, we will focus on the second term, or the force that is exerted by your feet on the earth. To get a better understanding of this term, we will now use the acronym, G CM.
The force-displacement formula for the G CM equation is as follows: where T is your total body weight, c is your center of mass, and d is the distance between your left foot and the center of your body with your right leg in the air. This formula gives you the amount of energy that is stored in your leg muscles, which can only be depleted when you get too much air pressure on your feet. Find your G CM by finding the force on your feet on the ground that causes the lowest total energy storage. You may find that this point is right between your feet touching the ground and your center of mass.
