Question

How are distance and force related?


When distance is increased the amount of force needed will increase.

When distance is increased the amount of force needed will remain the same.

When distance is increased the amount of force needed will depend on the mass of the object.

When distance is increased the amount of force needed will decrease.

Answer 1

When distance is increased the amount of force needed will remain the same.

The amount of force needed to move an object doesn't change with distance. However, the amount of work required obviously does...

Answer 2

O My Gosh you are my super hero right now! THANK YOU SO MUCH

Answer 3

:)

Also, remember that \[F=mass * acceleration\]...which also shows you that force is not related to distance.

Answer 4

Force depends on acceleration, and acceleration is related with distance.(remember s=ut+at^2/2)? A greater acceleration will make a body cover a greater distance in a particular time.
So if time is considered constant(also the initial velocity) I think the force will depend on the mass of the object on increasing distance

Answer 5

Force of what? Distance to what?

Answer 6

@Mani_Jha: I mispoke, acceleration does relate back to distance but in this case I don't see how it matters. The force it takes you to move something doesn't change with distance...it still takes the same force to move something 1m as it does to move it 1000m. The only difference in the two scenarios is the amount of work done.

Answer 7

and also the time taken. I think the question should have stated whether time should be considered constant. If the time is constant, then the force will be larger. I mean it will take a larger force to move a object by 1000m than by 1m in the same time.

Answer 8

I can agree with that :)

Answer 9

Given the wording of the question and available answers I think the one I chose is correct though.
