Introduction
We use the word work in a a variety of contexts in our daily lives. But what is happening in every sector of the workplace. It works in our everyday lives, but not in the language of physics. Work has a specific definition or meaning in the language of physics. that is, in order to conduct any labor, some form of force must be given to the object and it must be moved from one location to another, or the distance must be adjusted. Then it’ll work in physics terms. In physics, we say that an objects work is done if the force given to it moves the object across a distance.
Defintion: When a force is applied to an object or a person and the or person moves towards the force, the force’s distance traveled is referred to as work. That is, if a force F is applied to an item and a person or object moves a distance s toward it, the force will do W of work.
So, W= Fs
The unit of work is the joule. Work is considered a scalar quantity because it has no direction. If a force of 1N applied to an object, the work done is 1J if the item moves one meter towards the force.
In our daily lifes, we do a variety of tasks, some of which require force. That is we use various sorts of force when working, which might come from anything, any person or any machine. As a result, we can perform many types of tasks. However, in the termology of physics, applying force to an item or a person results in work being done. If an object or person not change its position even the after applying any type of force, then there will be no work in the language of physics.
Examples of work
When we ride a bicycle, we exert force and produce work. Answer, we are not doing any work. Even when we employ force, no task is completed because there is no change in our location. However on the bicycle, we exert force, wehich causes the bicycle to move from one location to another. That is the bicycle is doing the work for us.
Again, we wish to get from one location to another by pusing a wall. Our bodies sweated as we applied additional force, but we were unable to move the wall. Then no work was accomplished by us. If we apply force to shift the wall one location to another, we will have completed the work.. Because there is no change of location, no job is completed.
Again, we trave from one location to another, work will be completed here. We are going from one location to another using force. Again, if we stand in one location, no job will be completed. Because I’m not covering any distance. In a nutshell, work is done when a person or thing moves from one location to another or alters the distance.
Mathematical examples of work
Considering the following work example: a person dragging a mass (m) with a force (F) at an angle (θ). What amount of work is done when m moves the mass a distance s? If the mass is dragged by a force at a right angle, the work done by the person through the distance θ from the plane is W= Fscosθ.
Another thing to keep in mind is that the mass has a weight, which is a ball; its number is mg, and it acts downward. If the force mg and distance s are at an angle θ, the amount of work done id W= mgscosθ. Assume the force mg and distance s are at a 90° angle. The quantity of work is calculated as mgscosθ= mgscos90°= mgs × 0 (cos90°=0)= 0, resulting in a value of 0. If any distance is perpendicular, no work is done and the force does no work either. If several forces can be applied to an item or person at the same time, the force can perform many funstions.
