Can a body be in equilibrium when only one force act on it?

Can a body be in equilibrium when only one force act on it?

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

Can an object ever be in equilibrium if the object is acted on by only a single nonzero force?

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 a body be in equilibrium when three forces are acting on it?

A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply : The lines of action are coplanar (in the same plane) The lines of action are convergent (they cross at the same point) The vector sum of these forces is equal to the zero vector.

Can a body be in equilibrium if it is in motion explain?

Yes, a body can be in equilibrium if it is in motion. We know that a body is said to be in equilibrium if the net force acting on it is zero. By the second law of motion, we know that the acceleration in such bodies is zero. No acceleration implies constant velocity.

Why a body Cannot be in equilibrium under the action of a single force?

Since there is a single force acting on the body and no other force to balance it, therefore, it will produce acceleration in the body (in accordance to Newton’s second law of motion) and the body will not be in equilibrium.

When all the forces on a body are in equilibrium the body is?

zero
When any object is in equilibrium, the sum of all the forces acting on it is zero.

When a body is in equilibrium under 3 non-parallel forces they must be?

If a body is in equilibrium under the action of three non-parallel coplanar forces, the forces must be concurrent, that is, must meet at a single point.

Can a body be in equilibrium while in motion if yes give example?

Yes, if body has no linear and angular acceleration. Hence a body in uniform straight line motion will be in equilibrium.

Why Cannot a body be in equilibrium due to single force acting on it?

In general for a body to be in equilibrium it must have no forces acting on it or all forces must act upon the body in such a way they cancel themselves out. This can not happen with just one force as there isn’t another force to balance this force.

Is it possible to be in equilibrium with only one force?

In other words, if we want to be in equilibrium with only one force, it must be that the force is 0 (there is no force! A contradiction to the assumption that we have one force acting on the body). So, we see that we cannot be in equilibrium with only one force acting on the object.

What does it mean for a body to be in equilibrium?

By definition equilibrium means equal or balanced. In general for a body to be in equilibrium it must have no forces acting on it or all forces must act upon the body in such a way they cancel themselves out. This can not happen with just one force as there isn’t another force to balance this force.

What is a special case of equilibrium?

A special case of equilibrium exists when there are no forces on the object, since this satisfies the condition of sum of forces equals zero. If there is one force present, the object cannot be in equilibrium. The object will change velocity in the direction of the force. Equilibrium of an object is achieved when the sum of forces equals zero.

What is the difference between equilibria and acceleration?

Equilibrium occurs when there is no acceleration, which occurs when there is no net force. If there is only one force acting on the object, then the net force is not 0 and the body is therefore not in equilibrium.
