\[W = Fd\]
Variables
Wmechanical work (J)
Fconstant force parallel to motion (N)
ddisplacement (m)
Description
What is this formula?
The mechanical work equation calculates the energy transferred when a constant force moves an object through a displacement in the direction of the force.
When to use it
Use this formula when analyzing lifting systems, pushing or pulling objects, industrial machinery, transportation systems, or energy transfer in mechanical systems.
Example
A constant force of 250 N moves an object 12 m along a horizontal surface.
Data:
F = 250 N
d = 12 m
Formula:
W = F*d
Substitution:
W = 250*12
Result:
W = 3000 J
Applications
Mechanical engineering, industrial machinery, transportation systems, lifting equipment, robotics, and physics education.
