# First peerson to define work as W = F d.

• carvajal57
In summary, Gustave-Gaspard Coriolis (1792-1843) was the first person to define work as W = Fd, and his contributions to the concept were examined in detail by I Grattan-Guinness in 1984.

Please, can someone tell me who was the first person to define work as we currently use, that is, W = F d? Thank you.

According the article below, it was Gustave-Gaspard Coriolis (1792-1843) who:
"The modern statement: "work is force times path" is due to French physicist Gustave-Gaspard Coriolis,[1] who gave the correct formula for change in kinetic energy associated with work[/quote]

The acclaimed website, MacTutor History of Mathematics Archive,

has the following biography on him:

From the MacTutor biography, we learn of an article from 1984 that examines in detail the relative contributions of Poncelet, Navier and Coriolis to the concept of "work":

"I Grattan-Guinness, Work for the workers : advances in engineering mechanics and instruction in France, 1800-1830, Ann. of Sci. 41 (1) (1984), 1-33."

## What is the significance of defining work as W = F d?

The equation W = F d is significant because it provides a quantifiable way to measure work, which was previously thought of as a vague concept. It allows for a clear understanding and comparison of the amount of work being done in different situations.

## Who was the first person to define work as W = F d?

The first person to define work as W = F d was the French mathematician and physicist, Gaspard-Gustave Coriolis, in 1829.

## Is the equation W = F d still valid in modern science?

Yes, the equation W = F d is still considered valid in modern science and is used extensively in physics, engineering, and other scientific fields.

## What are the units of measurement for each variable in the equation W = F d?

The unit for work (W) is joules (J), the unit for force (F) is newtons (N), and the unit for distance (d) is meters (m).

## Can the equation W = F d be applied to all types of work?

No, the equation W = F d is specifically applicable to work done by a constant force in a straight line. For more complex situations, other equations and principles must be used.
