Total Work Calculator

Enter the values in the given input boxes to calculate the total work in physics using the total work calculator.

Work and Total Work

To calculate Work:

    • kg
    • m/s2
    • m/s2

Total work done can be calculated with ease using this online work calculator for physics. It requires mass, initial velocity, and final velocity of the object to get the total work done.

In this space, we will explain definition of total work, how to find work for physics problems, work equation for physics, and few examples to calculate work.

Work formula

Are you looking for work physics formula?

Work formula is generally used in physics to find the work done by an object. The work done formula can be expressed as:
W = Fd

Where,
W = Work,
F = Force, and
D = Distance

Work with change in velocity

Here is the formula to calculate work from change in velocity.

WT = 1/2(mvf2 − mvi2)

Where,
WT= Total Work,
m = Mass,
vi= Initial Velocity,
vf= Final Velocity.

What is work?

Work is the energy transferred to or from an object by applying the force along with displacement. In other words, it is generally represented as the product of force and displacement.

S.I unit of work is Joule J or Newton-meter Nm.

Work = force x distance

How to calculate work?

Calculating work is absolutely simple, either you use work done calculator or above-mentioned formula for the calculation.

Example: Work with force and displacement

Find the work done by a car if the force applied on the car is 20 N with a displacement of 500 m.

Solution:

Step 1: Write down the values.

F = 20 N

d = 500 m

Step 2: Use the work done formula and place the values.

W = F×d

W = 20×500

W = 10,000 J

Example: Work with velocity change

Find the total work done, if the initial velocity of an object is 10 m/s, final velocity is 50 m/s, and mass is 20 kg.

Solution:

Step 1: Write down the given values.

vi = 10 m/s

vf = 50 m/s

m = 20 kg

Step 2: Write down the work formula for change in velocity and place the values in it.

WT = 1/2(20×502 − 20×102)

WT = 1/2(50000 − 2000)

WT = 1/2(48000)

WT = 24000 J
