If 2 force act on the object in the same or opposite directions what willbe the net force of the object in 2 cases?
There is no net force OF the object. If the forces act in the same direction, the net force is magnitude of the net force is the sum of the forces and acts in the same direction. If the forces act in opposite directions, the magnitude of the net force will be the difference between their magnitudes and it will act in the direction of the larger of the two forces.

The force of friction is directed opposite of the way an object is moving because?
The force of friction is NOT ALWAYS directed opposite the direction an object is moving. Consider, for example, an object (like a book) resting on a piece of paper on a table. If you gently pull the paper and the book moves with the paper, friction between the paper and the book is causing the book to move in the same direction as the paper. Even if you pull a bit faster and the book slides in the same direction as the paper motion, but a little bit slower, the friction is the force which is pulling the book along--in the same direction of the paper motion.The direction friction is acting is opposite the direction of the relative SLIDING or attempted sliding of surfaces. In the cases above, without friction, the book would slide opposite the direction of paper motion, so the friction is in the same direction, accelerating the book along with the paper. In the first case, the book's acceleration is the same as the paper's; in the second, the book's acceleration is less than the paper's causing the book to actually slide backwards relative to the paper's motion.
How do balanced and unbalanced forces affect an object at rest?
they cause the object to move with acceleration given by A nett force.
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 4 things happen to light when it hits an object?
it can be transmitted, reflected, refracted or diffused. In most cases, some combination of these occurs.
Why you fly forward off the bicycle or skateboard when hitting a curb or rock or other object that abruptly halts the motion of the bike or the board?
Its called inertia. It takes work to stop an object that is moving, if you don't have any (as in the cases mentioned), you keep on moving.
How the reaction force will act on an object while pulling and pushing the object placed on a table?
When pulling an object on a table, the reaction force will be equal and opposite to the pulling force exerted on the object. When pushing an object on a table, the reaction force will be equal and opposite to the pushing force exerted on the object. In both cases, the table exerts a reaction force to prevent the object from moving.
How do you know that the forces acting on an object are balanced?
If an object is at rest or moving at a constant velocity, the forces acting on it are considered to be balanced. This is because in such cases, the net force acting on the object is zero, meaning that the forces are equal in magnitude and opposite in direction.
What is the opposite of uninformed?
The opposite is "informed." In some cases, the opposite could be aware, cognizant, or knowledgeable.
What is the opposite of dark?
The opposite (colors or illumination) is light. In some cases, the opposite would be "bright."bright
Are there cases in which force is not necessary for an object to move?
no
What the opposite of 3?
The opposite of 3 is -3 (minus three).
What is a drag in what situations might it act on the force of gravity?
Drag is a force that acts in the opposite direction of an object's motion through a fluid (liquid or gas) and is caused by the interaction between the fluid and the object's surface. Drag can impact the force of gravity acting on an object when the object is either falling or being propelled through the fluid. In both cases, drag can either increase or decrease the net force of gravity acting on the object.
Is a quadrilateral with two opposite side but not equal?
All quadrilaterals have two [pairs] of opposite sides and in most cases they are not equal.
When an object at rest explodes into two part fly apart must they move in exactly opposite directions(b) when a moving object strikes a stationary one must they move off in exactly opposite directions?
Very few questions are this much challenging to answer! The answer is no. Both parts can move in any direction including the opposite direction. The final outcome will depend upon the amount of energy released by the explosion. The amount of energy taken in by the breakage of the object. ( The rest of the energy will be taken up by the two objects to move away from each other.) Whether the explosion takes place at the center of gravity or away from it. When explosion takes place at the center of gravity, two parts will be driven away from each other. If the explosion takes place away from the center of gravity, then the whole piece will together move away from the explosion point in opposite direction of the explosion point. The final direction of the two parts will be decided by the center of the gravity of the both parts. There are very less chances that both the parts will move in opposite direction. In most of the cases both parts will move away from each other making an angle. The bigger part will move away with less speed. It can be further explained with the help of the diagram and trignomentry. In day today life you have got a gun. Here in explosion takes place inside the barrel. It seems that the bullet and the gun move in opposite direction. It is true. But the direction is not exactly opposite. It is roughly opposite. Here the bullet takes a high speed. Because it has got a less mass. The gun also gets a recoil. As you can feel the thrust in case of rifle on your shoulder. When both the parts move away in opposite direction, the product of mass and velocity is same. Now the second question is very easy to answer. You see that in day to day game of carrom board or the billiard. Here you strike at the periphery of the ball and both of them move away by making an angle. Here also the angular momentum plays a role.
In newtons 3rd law how many forces always act at once?
Two - forces act in pairs. If object "A" acts on object "B", the object "B" will also act on object "A". In many practical situations, there may be additional forces involved. For example, if an object is at rest despite the fact that a force acts on it, then it is obvious that an additional force acts on the same object, and in the opposite direction. In such cases, there are at least four forces involved, since according to Newton's Third Law, there must be an opposite force for each of these two forces. (Note that in Newton's Third Law, the two forces act on DIFFERENT objects, so the two forces that hold an object in balance do not quality as a pair of forces according to Newton's Third Law.)
How can the net force be zero if there are many forces acting as an object?
if their vector sum is zero it is in equilibrium with no net force. For example if you push in one direction with a force of 10 pounds and someone else pushes with 10 ponds in the opposite direction net force is zero
What happends if a asteroid collides with an object?
The result wold depend on the energy created by the collision. In most cases both objects would shatter into pieces that would spin away in a variety of new directions. If the asteroid collides with a much bigger object (a planet) then it will create an impact crater in the planet and the asteroid and a bit of the planet's surface will melt.
