Question

watch this 2 - minute video, then answer the question: is there a difference between the work we describe in science and the work you do to earn money?
your post should include:

• a well - thought - out explanation (2.5 pts)
• a real - life example (2.5 pts)

Explanation:

In science, work is defined by the formula \(W = F\times d\times\cos\theta\) (where \(F\) is force, \(d\) is displacement, and \(\theta\) is the angle between the force and displacement vectors). So, if you push a wall and it doesn't move (\(d = 0\)), in scientific terms, no work is done. However, when you do work to earn money (like typing on a keyboard - your fingers apply force and there is displacement of the keys, or a waiter carrying plates and walking - force against gravity and displacement in the horizontal direction where component of force in the direction of displacement exists), there is often a physical displacement involved that can align with the scientific work formula. But the key is the scientific definition is very specific based on force and displacement, while work to earn money is a broader social - economic concept that usually (but not always) involves physical actions that can be related to scientific work.

Answer:

Yes, there is a difference. Scientific work is based on the formula \(W = F\times d\times\cos\theta\). For example, if you hold a heavy book in your hand without moving it, in science, no work is done (\(d = 0\)). But if you are a librarian getting paid to carry books from one shelf to another (force applied to lift the books - component of force in the direction of horizontal displacement as you walk), while the work - to - earn - money concept is about the task for payment, the scientific work calculation is satisfied here as \(F
eq0\), \(d
eq0\), and \(\theta\) (angle between lifting force and horizontal displacement) has a \(\cos\theta\) component (since the vertical lifting force has a horizontal displacement component when you walk, work \(W = F\times d\times\cos(90^{\circ}-\text{angle of your body movement})\)). So, scientific work is a precise physical calculation, while work to earn money is a task - for - payment concept that may or may not involve scientific work (but often does in physical labor jobs).
