Question

Using the scientific definition of work, does a greater amount of force always result in a greater amount of work? Why or why not?

Answer 1

no because work is also proportional to the distance over which the force acts.
if, for example, you have a 10N force acting over a distance of 1m we have 10(1)=10J of work being done.
if, however, you have a force of 20N acting over a distance of 0.2m, the resulting work done is 20(0.2)=4J, which you can see is less than the work done by the 10N force in my example.

Answer 2

Thanks . ^_^

Answer 3

Work is actually proportional to displacement i.e, distance in a specified direction

Answer 4

Not the net displacement, necessarily...

Answer 5

If you want to be really rigorous about it,
\[\text{An infinitesimal amount of work } \delta W \text{ is proportional} \]
\[ \text{ to the infinitesimal displacement }\delta r \text{ over which the force in question acts.}\]

Answer 6

But given the nature of the question, I doubt that's necessary :)
