MHB What is the dot product formula for constant force work?

AI Thread Summary
The work done by a constant force is calculated using the formula W = F s cos(θ), where F is the force, s is the displacement, and θ is the angle between the force and displacement vectors. This formula can also be expressed using the dot product of the force and displacement vectors as W = F · s. The dot product simplifies the calculation by incorporating both the magnitude of the vectors and the angle between them. Understanding this relationship is crucial in physics for analyzing work done by forces. The dot product is a fundamental concept in vector mathematics applied in various physical scenarios.

Re: Constant Work formula

The work $W$ done by an agent exerting a constant force is the product of component of the force in the direction of the displacement and the magnitude of the displacement of the force:

$$W=Fs\cos(\theta)$$

It is sometimes convenient to express this equation in terms of a scalar product of the two vectors $\textbf{F}$ and $\textbf{s}$. We write this scalar product $\textbf{F}\cdot\textbf{s}$. Because of the dot symbol, the scalar product is often called the dot product. Thus we can express the equation above as a scalar product:

$$W=\textbf{F}\cdot\textbf{s}=Fs\cos(\theta)$$
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
