Only the mugging concept in physics won’t give you much benefit, as the implementation of the concept can do. So we have covered the work done, work in thermodynamics, and work formula in terms of energy so far. Thus the SI unit of work and energy is the same, and the SI unit of work and energy is Joule(J). It shows that the work is the movement of energy.

Let’s calculate the work done through gases against a constant external pressure by taking reference to the formula we have studied lately. This process is also known as Pressure-Volume or PV. The work in gases can be done by expansion or compression against constant external pressure. As we already studied, work is some sort of energy required to move an object in the direction of the force.

Here we will see the work formula in thermodynamics and also we will know how to calculate work done by the compression or expansion of a gas. Read: Velocity Formula Work Formula in Thermodynamics If one joule of work is done, the formula for work is 1 J = 1 N.m. Θ= is the angle formed by the force and displacement. The formula of work is given below:ĭ = The magnitude of the displacement in the force’s direction. Hence, work is a scalar quantity and its SI unit is Joule which is represented by J. Both are vector quantities, which means work is the dot product of two vectors and we have studied in physics that the dot product of two vectors produces scalar quantity. Work is the product of force and displacement. The formula of work is employed to calculate the work done to displace any object. Read: Percentage Error Work Formula dimension in Physics If the box will not displace a bit from its actual position p to new position q then the work done will be zero. Lets more simplify the definition of work with an example, suppose a box is placed at the position “p” and when we push the box in forwarding direction, that means we are applying force to the box and the box moved to the new position “q” that means its displaced from p position to q position. If there is no displacement in the object then the work done will be zero. When we apply any force to an object and the object is displaced by its actual position in the direction of force then the work is said to be done.
