Formula for Work Done
The product of the magnitude of applied force and the distance travelled by the body equals the total work done by this force.
The formula for scientifically completed work will be as follows:
W = F·d
The force acting on the block is constant in this example, but the direction of the force and the direction of displacement impacted by it are not. Force F reacts at an angle θ to the displacement d in this case.
W = (|F| cosθ) |d|
where,
W is the work done by the force.
F is the force,
θ is the angle between the force vector and the displacement vector,
d is the displacement caused by the 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.
