Work Calculator Physics | How to Calculate the Amount of Work Done by Forces

Physics is at the heart of the research of how things travel, in addition, to be a term that sadly scares off possible future science lovers in anticipation. This encompasses everything from large galaxy clusters to objects almost too small to consider, far less to perceive adequately.

And a big part of applied physics (i.e., the physical science division concerned with using information rather than “simply” theorizing) is working out how to get more work with much less energy.

What is work in physics?

In physics, whenever we push or pull a body to make it move as a consequence of a force imposed on it, we said that work is done on that body. Work is any sort of function, task, or activity we carry out in our daily lives.

Nevertheless, doing work in physics has a very distinct, specific, and simple meaning. In brief, work is performed on the object if energy is used to help an intended action.

Some examples of work

Lifts moving hotel guests up to their floors, a boy pushing a cart up a mountain, or flowing petrol in a steam engine and pushing a piston are daily examples of work being undertaken.

It is beneficial to study some of the principles of energy, movement, and substance that render “work” a feasible idea in physical science in the first place to better grasp this notion.

The general formula for work

The work concept in physics can easily be understood by its general work formula. The work formula is written as

W = F x d

A standard unit for work

According to the formula or work equation, where the work is W, the force applied is F, and the displacement is d. The Joule (J) is the regular standard unit for function.

Or in other words, work may be said to be an energy transition or a change in the kinetic energy of any of the body.

Relationship of work and energy

It is obvious that you pass energy to the subject that you have worked on as someone or something puts some kind of force on it. Heat is wasted in form of friction in the physical world; this may be considered as the resistance among objects, between molecules of fluid, or both.

Work is equivalent to energy transition in idealized physics situations where friction is ignored. An object lying on the planet at the ground surface will be an example of this. This is because it has no height to fall, it has zero gravitational potential energy.

If we work on it by moving it off the ground vertically, the potential gravitational force would be equal to the work we have performed on it.

When work is done in some direction

We use the standard work equation when force is applied to any of the body in the same direction that it is displaced as above.

When the applied force as well as the direction of displacement of the body is not in the same direction, then the work equation can be represented as,

W = F × d × cos(θ)

Here W is referred to as work, F is referred to as the force applied on the body, θ is the angle between the directions of force application and body displacement, and d represents the displacement.

Work equation – how to calculate work?

When we talk about finding out the work by using its equation, then the calculations are quite simple just as the formula. The force and the distance that the body cover in response to the applied force is all you need. Multiply both force and distance values and the outcome will be the work that is done on the body.

Solved example:

Finds out the Work if the applied force is 30 newton and the displacement it covered is 12 m.

Solution

Force (F) = 30 N

Distance (d) = 12 m

The formula for work:

W = F x d

By putting values of force and displacement

W = 30 x 12

W = 360 J

Work (W) = 360 Joules

There is another advanced and fancy way to solve the work equation and that is adding up the force equation f=ma into the work equation and it will become

W = m x a x d

This equation is applied to the condition when in place of force the values of mass and acceleration of the body are provided.

This method is as simple as the standard work equation because it is a simple multiplication that can be solved instantly.

If you still find this method hectic for you. Don’t you worry! We have covered you here. The work calculator from can solve the work equation and finds you out exactly the amount of work that has been done.

How to use the work calculator?

The meracalculator’s work calculator is fairly convenient and simple to use. It finds out the work equation in its basic or standard form, all it asks you is simply the force in newton and the distance in meters and it will automatically find out the result in joules for you.

This advanced calculator can mold the equation into three different forms and also gives you options for finding the distance and force along with the work calculations.

First of all, you need to select the option from these three modes of calculation that will allow you to determine the value you need.

• For the calculations of work, it will ask you to input the force and distance.
• For the force calculations, you have to put the values for work and distance.
• And for distance calculations, putting the values for work and force.

This is how easily this calculator operates.

The online calculators for this job is intelligent. It claims to find out work and all other possible values in no time, once you had put the required values into the input fields. It would give authentic results immediately.
