Factors Affecting Work
Various factors affect the work done by an object which are,
- Force applied
- Displacement
- Angle Between Force Vector and Displacement Vector
Let’s look at some of the factors that affect the work done by an object.
Force Applied
It is described as a push or a pull that may cause any massed object’s velocity and acceleration to alter. The amount and direction of force are both vector quantities. If the force acting on an item is zero, regardless of whether the object is in a dynamic or static state, the force does not work.
Displacement
It is a vector quantity that represents the smallest distance between an object’s starting and final positions. The net work done by a force acting on an item is zero if the resultant displacement in the direction of force is zero. For example, if we push a hard wall with all our might but still fail to move it, we might say we have done no work on the wall.
Angle Between Force Vector and Displacement Vector
Depending on the direction of displacement of the item with regard to the force, the work done by the force might be positive, negative, or zero. The work done by the force of friction on an item moving in the opposite direction to the direction of force, such as friction acting on an object travelling forward, is negative. When the angle of displacement is perpendicular to the direction of the force, an item experiences zero force.
Work Done
Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. In our daily life, we do work and get tired. Even if we are doing our work while sitting on a chair, we say we have done a lot of work and got tired. But this is not the work done as per the definitions of physics.
In this article, we will learn the definition of work in terms of physics and the factors on which work depends.
