When 2 or more forces cancel their effect?
When two forces cancel each other, they are called balanced forces. Nothing happens when balanced forces are involved. Motion and anything else relating to force can only happen when there are unbalanced forces involved. If there are two opposite but unequal forces, then there is a net force. The net force is the difference between the two forces, and it acts in the direction of the strongest force. For example, if there are two people pushing on the same box in opposite directions, and one exerts 10 newtons of force, and the other exerts 15 newtons, then the net force will be 5 newtons, and it will be in the direction of the force applied by the person exerting 15 newtons.
What are forces expressed in?
Forces are expressed in newtons....i believe...
What is it called when two forces go in the opposite direction?
If the forces are equal then the net force is 0. If one force is greater than the other than whatever is having the two forces exerted on it will move in the direction of the greater force's direction. The total force will equal the greater force - lesser force. You can draw it in vectors to help visualize. e.g. F1 <------------------*-------> F2 let's say F1 = 5 newtons and F2 = 2 newtons. The combined force would equal 3 newtons going <- direction.
What are forces that always act in equal but opposite pairs?
If the equal and opposite forces are separated by a certain distance they are called as couple. If the equal and opposite forces are not seperated by a certain distance their resultant is zero as per Parallelogram Law of Vector Addition.
What happens to an object's motion when 2 equal forces act on an object in opposite directions?
Nothing! If the two forces are equal and opposite then they will cancel each other out. What will happen next is described in Newton's First law when it says "An object in motion will stay in motion unless acted upon by an outside force". Two equal and opposite forces have the same effect as no force, therefore the object's motion will remain the same as if it had never been acted upon by the two opposite forces.
When forces act in opposite direction?
When two equal forces act in opposite directions, they are called balanced forces, and no motion takes place. If they are unequal, than the weakest force is cancelled out, along with an equal amount of the strongest force. For example, if an object is being pushed on opposite sides with 7 and 10 newtons of force, then the 7 newton force will be entirely cancelled out, along with 7 newtons of the 10 newton force. This will leave a net force of 3 newtons acting on the object. If there is a net force (also called an unbalanced force), then motion will take place.
According to newtons third law forces always occur in what pairs?
equal but opposite

If forces on an object are equal and opposite then what are they called?
They are called COUPLE.if forces on an object are equal and opposite...
In newtons third law the action and reaction forces?
The two forces are of the same magnitude, act in opposite directions, and act on different objects.
How does newtons law of motion relate action and reaction forces?
For every action there is an equal and opposite reaction.

What is for net force of 100 netwons pushes against a forces of friction of 80 newtons?
Since the forces act in opposite directions, just subtract them.
If Two horses pull againts a rope with forces 100 newtons in opposite directions this is an example of?
Balanced Force.
What is the net force and acceleration of a ball of mass 0.750 kilograms that is subjected to forces of 11.00 newtons and 7.00 newtons from opposite directions?
Net force: Add the forces algebraically. In this case, since they are in opposite directions, you subtract. Acceleration: Use Newton's Second Law: F = ma. Solving for a: a = F/m.
The vector sum of 3 newtons and 4 newtons?
It depends on the angle between the two forces. It can be anything from 1 newton (if they're acting in exactly opposite directions) to 7 newtons (if they're acting in exactly the same direction).
How are forces forces measured?
newtons
