Total Work Formula
The following formula is used to calculate the Total Work.
Wtotal = 1/2*m*(Vf^2-Vi^2)
- Where Wtotal is the Total Work (Joules)
- m is the mass (kg)
- Vi is the initial velocity (m/s)
- Vf is the final velocity (m/s)
How to Calculate Total Work?
The following example problems outline how to calculate the Total Work.
Example Problem #1
- First, determine the mass (kg). In this example, the mass (kg) is given as 10 .
- Next, determine the initial velocity (m/s). For this problem, the initial velocity (m/s) is given as 30 .
- Next, determine the final velocity (m/s). In this case, the final velocity (m/s) is found to be 40.
- Finally, calculate the Total Work using the formula above:
Wtotal = 1/2*m*(Vf^2-Vi^2)
Inserting the values from above and solving yields:
Wtotal = 1/2*10*(40^2-30^2) = 3500 (Joules)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:
mass (kg) = 5
initial velocity (m/s) = 40
final velocity (m/s) = 60
Enter these given values yields:
Wtotal = 1/2*5*(60^2-40^2) = 5000 (Joules)
