Total Work Calculation

Total work done Calculator

Total work done calculator is used to calculate the total amount of work done. It takes the values of mass, initial, and final velocities and gives the total work in a fraction of a second.

What is total work?

The change in a particle's kinetic energy equals the work W that the resulting force has on it. If v_i and v_f represent. The initial and final velocities correspond to the start and stop of the interval.

WT = ½ (mvf2-mvi2)

How to calculate total work?

In this section with the help of examples, the tool will be explained.

Example 1

Find the total work done if the initial velocity of an object is 6 m/s, the final velocity is 10 m/s, and the mass is 2 kg.

Solution

Step 1: Write the given values.

m = 2 kg

v_i = 6 ms^-1

v_f = 10 ms^-1

Step 2: Take the formula and substitute the values in it.

WT = ½ (mvf2-mvi2)

W_T = 1/2(2×10² − 2×6²)

W_T = 1/2(200− 72)

W_T = 1/2(128)

WT = 64 J

Example 2

Calculate the total work done, if the initial velocity of an object is 5 m/s, the final velocity is 7 m/s, and the mass is 4 kg.

Solution

Step 1: Write the given values.

m = 4 kg

v_i = 5 ms^-1

v_f = 7 ms^-1

Step 2: Take the formula and substitute the values in it.

WT = ½ (mvf2-mvi2)

W_T = 1/2(4×7² − 4×5²)

W_T = ½*4*(49-25)

W_T = 2(24)

WT = 48 J
