Want this question answered?
You just stated the 3rd law of newton which states that every action has an equal and opposite reaction. This basically means that anything you do has to be reacted upon back. even more simply put, if an action has to take place (like jumping from a boat) then an equal force of action acting in the opposite direction also has to take place (the boat moves back).
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.
gravity
Since the opposite force is the strongest the object will tend to change direction of the object.Thats one of the effects of force.
Forces are vector quantities. This means they have both a magnitude and direction associated with them. If you add vectors going in the opposite directions it is the same as subtracting one from the other. Therefore, the resultant force is the difference between the forces.
A force of equal magnitude, acting in the opposite direction.
as adding a ".... in the opposite direction.
It is the same as adding a positive and adding a negative number
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.

A negative force. Since the force added in the opposite direction works against the original force, you would subtract the added force from the original force. Since subtracting a positive is the same thing as adding a negative, this force would be considered negative to the positive direction.

In principle, any force acting on an object is unbalanced, UNLESS there is a second force in the opposite direction, acting on the same object.

It is called a reaction force. The question you have asked is paraphrase of Newton's third law of motion. Action and reaction are always equal but opposite in direction.
A negative force. Since the force added in the opposite direction works against the original force, you would subtract the added force from the original force. Since subtracting a positive is the same thing as adding a negative, this force would be considered negative to the positive direction.
You must first choose which direction you shall call positive, thereby the opposite direction shall be negative. Then you add these two values together to get your answer, the total net force.
