7 N east
45 N north.
If the 10N force is positive, meaning to the north, then the 5N south would be negative, and the net force is 10N + (-5N) = 5N to the north.
5 N to the north.
You can't, unless you know both of their directions. -- If they're in the same direction, then the net force is 10N in that same direction. -- If they're in opposite directions, then the net force is zero, and the direction doesn't matter because there's no net force. -- Depending on their directions, those two forces can combine to produce a net force of anything between zero and 10 N, in any direction. So you need to know their directions in order to figure out what the net force is.
This would be known as the net-force.
Inertia will not be affected when "net" or "net force" is zero.
If the 10N force is positive, meaning to the north, then the 5N south would be negative, and the net force is 10N + (-5N) = 5N to the north.
Balanced forces means the net force is zero, but net force can also be positive or negative numbers. If I pull a block with a force of 10N to the right, and you pull it with a force of 10N to the left, the net force on the block is zero, thus balanced forces. If I start to pull with a force of 20N to the right, but you still pull 10N to the left, the net force on the block is 10N to the right, thus causing acceleration of the block to the right, thus unbalanced forces
The net force is the difference between the 10N falling object and the 4N of air resistance So you solve 10N-4N is 6N
30
No, only a force direct West can balance a force directed East.
5 N to the north.
Since it is in one dimension, you add as you add real numbers, either 10 + (-20) (if you call east positive), or -10 + 20 (if you call west positive).
25-15= 10n
the net force is 10N - it is acceleratiing with gravity - if no air resistance. If it falls far enough, eventually air resistance will balance the force and net force will be zero - it will fall at constant velocity and zero acceleration
Take east to be the positive direction, +11 lb. Take west to be the negative direction, -17 lb. Resultant (net force) = +11 lb + (-17 lb) = -6 lb, or 6 lb west.
10N south would be the force exerted
If you let northward be a positive force and southward be a negative force, you could add the two forces in this manner: +10N + -15N = -5N This gives you not only the magnitude of the net force, but also the direction: 5N southward.
