Question

Which of the following sets of forces acting on an object will result in the object moving?

5 Newtons Up and 5 Newtons Down
31 Newtons Left and 32 Newtons Right
0 Newtons Up and 0 Newtons Down
9 Newtons Left and 9 Newtons Right

Answer 1

the answer would be the 2nd option given: 31 newtons left and 32 newtons right because you go an extra newton to your right, which moves the object

for option #1, if you were to go 5 newtons up and 5 newtons down, you’d end up at your starting point again.

for option #3, going 0 newtons up and 0 newtons down results in no movement at all

for option #4, going 9 newtons left and 9 newtons right would result in, once again, ending on your starting point

Answer 2

31 Newtons Left and 32 Newtons Right

Step-by-step explanation:

If two forces are applied to an object in opposite direction, it will be moved only if the set of forces are not in equilibrium.

Forces going in opposite direction with the same strength are in equilibrium, like first, third and fourth options.

But, if the forces go in opposite direction with different strength, they are not in equilibrium, like in the second option. In this case, there is a net force going to the right, equal to 32 -31 = 1 Newton.
