Is it possible for an object not to be in equilibrium when the net force?

– If the net force on an object is not zero, it is not in equilibrium (that is, a change in velocity will occur), and thus Newton’s Second Law must be used to determine its motion.

Can an object be in equilibrium no net force if it is acted on by only a single force?

The net force is then 20N – 12N = 8N. E19. If only a single nonzero force acts on an object, it will not be in mechanical equilibrium. There would have to be another or other forces to result in a zero net force for equilibrium.

Can an object ever be in equilibrium if it is acted upon by a single non zero force?

No: equilibrium requires forces to be balanced, so it requires (at least) two forces, unless there are zero forces acting.

Is it possible for an object to be in motion when there is a net force of zero acting on it?

If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it. Net force is the vector sum of all forces acting on the object.

Is it possible for an object not to be in equilibrium when the net force exerted on it by other objects is zero give an example?

Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. By Newton’s second law, the acceleration of such objects will be zero.

When an object is in equilibrium state then?

When all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium. The forces are considered to be balanced if the rightward forces are balanced by the leftward forces and the upward forces are balanced by the downward forces.

Is equilibrium necessary in any system of force?

The net force acting on the object must be zero. Therefore all forces balance in each direction. For example, a car moving along a highway at a constant speed is in equilibrium, as it is not accelerating in any forward or vertical direction.

Which of the following forces Cannot be in equilibrium?

Which of the following concurrent forces cannot produce equilibrium (1) 10 N, 15 N, 12 N. (2) 100 N. 120 N, 80 N. (4) 20 N, 30 N.

Can an object ever be in equilibrium if it is acted?

Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. Dynamic Equilibrium : When the net force acting on an object is zero and if the object is moving at a constant non-zero velocity, then it is called dynamic equilibrium.

What kind of force can be acting on an object in equilibrium?

If the net force is equal to zero, the object is said to be in equilibrium. Because there is no net force acting on an object in equilibrium, then from Newton’s first law of motion, the object continues to move at a constant speed.

Is it possible for an object to be moving in one direction while the net force acting on it is in another direction?

In general, the only reason an object will move in a different direction to the net force on it is because of its prior momentum. And it will always accelerate in the direction of the force.

Is it possible for an object to be in equilibrium?

Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. By Newton’s second law, the acceleration of such objects will be zero. Zero acceleration implies a constant velocity. Constant velocity also includes zero velocity as a special case.

What happens when the net force is zero in dynamic equilibrium?

Here the velocity is zero and remains unchanged. Dynamic Equilibrium : When the net force acting on an object is zero and if the object is moving at a constant non-zero velocity, then it is called dynamic equilibrium.

How many forces are acting on an object in equilibrium?

(e) There are at least two forces acting on the object. If an object is in equilibrium, which of the following statements is not true? (a) The speed of the object remains constant. (b) The acceleration of the object is zero. (c) The net force acting on the object is zero.

Is there such a thing as an unstable equilibrium?

If the net force on an object which is not already moving is zero, then it will not move. However, there is such a thing as an unstable equilibrium when the smallest movement will introduce some force which had not been present and the resulting motion will only increase that force.
