I'm not sure what you mean by 'force is needed'. Needed to do what?

The Newton is defined as the force required to accelerate a mass of 1 kg at a rate of 1 m/sec2. Clearly if you double the mass and keep the acceleration the same, the force required is also doubled.

What happens when the same force is applied to an object?

If the object was stationery before any forces were applied it will remain stationery, and if it was moving it will remain moving but at a constant speed. There is no resultant force so the object experiences no acceleration.


What are the effects on an object when two or more opposing forces of unequal mangnitudes are simultaneously applied to the object?

If there are two or more unequal forces acting on an object then the object will be acting on the forces. ^_^


The friction force that acts on objects that are at rest is?

If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.


How does the concept of Acceleration affect newtons 2 law?

Newton's second law of motion provides an explanation for the behavior of objects when forces are applied to the objects. The law states that external forces cause objects to accelerate, and the amount ofaccelerationis directly proportional to the net force and inversely proportional to the mass of the object.


What happens if a balanced forces are applies to a moving object?

When balanced forces are applied to a moving object, the object likely slow and eventually stop. How quickly that occurs depends on the amount of force.

What is the cumulative effect of the forces on the objects motion?

The cumulative effect of the forces acting on an object determines its overall motion. If the forces are balanced, the object will maintain its current state of motion (either at rest or moving at a constant velocity). If the forces are unbalanced, the object will accelerate in the direction of the net force applied.


How do unbalanced forces effect an objects motion?

If the [group of] forces on an object is unbalanced, the object accelerates.


How forces affects motion?

If force is applied in the line of motion, then motion will increase, but when it is applied opposite to the line of motion, then motion will decrease.


What effect do balanced forces have on stationary objects?

None. There is no effect on a stationary object.


Different forces are applied to two different objects that have the same s what will happen?

The objects will experience different accelerations based on the magnitude and direction of the forces applied. According to Newton's second law (F = ma), the acceleration of an object is directly proportional to the force applied to it. Therefore, the object that experiences the greater force will have a greater acceleration compared to the object with the lesser force.


How do balanced forces affect an objects motion?

Balanced forces applied on both sides of an object cause it to be still. Unbalanced forces will cause the object to move away from the strongest force.


What effect do balanced forces have on the motion of objects?

Balanced forces do not alter the motion of objects.


What are ways objects can accelerate?

Objects can accelerate through forces like gravity, friction, and applied external forces. Acceleration can also occur from changes in an object's direction or speed.


What can forces change the movement of objects?

Forces such as gravity, friction, and applied forces can change the movement of objects. Gravity attracts objects towards the Earth, friction opposes motion between surfaces, and applied forces like pushing or pulling can accelerate, decelerate, or change the direction of an object's movement.


Objects move when their what is changed?

Objects move when their balance is changed.


What are forces that do not cancel out or change an objects motion?

Some forces that do not cancel out or change an object's motion include net external forces, such as applied forces, frictional forces, and gravitational forces. These forces can cause changes in an object's motion, such as accelerating or decelerating it.


Balance forces have what affect on an objects motion?

"Balanced forces" means a set of forces that add up to zero.This group of forces acting on a single object have no effect on its motion, because they add up to zero,and their effect is equivalent to zero force on the object.
