How can a body be at rest but not in equilibrium?

A ball thrown vertically upward will be momentarily at rest even though a net force acts on it (and thus it’s not at equilibrium). A pendulum and an oscillating spring-mass are two more examples. Both cases show points of minimum velocity, which are as well the points at which maximum force and acceleration occur.

When a body is in state of equilibrium the body must be at rest?

At equilibrium the total external force acting on a body is equal to zero and external torque also must be zero. Complete answer: The word static means stationary. Thus the static equilibrium is attained when an object is at rest.

Which force keeps the body at rest?

Inertia is the property of a body to remain at rest or to remain in motion with constant velocity.

When we say the body is in equilibrium?

A body is said to be in equilibrium if it is at rest or moving with uniform velocity. In other words if the linear and angular acceleration of a body are zero, the body is said to be in equilibrium. When the net force acting on the body is zero.

When the body is in equilibrium Which of the following is true?

When the body is in equilibrium then which of the following is true? Explanation: Yes, we equate all the components of the three axis equal to zero. That is the resultant of the forces along the three axis are being equated to zero. This brings in that there is no net force in any direction.

Which of the following point is always at rest?

Answer: A fixed point of a body with respect to rest or motion is the reference point or the origin.

When a body is in equilibrium its acceleration is?

When the net force acting on a body is zero, its acceleration is zero. Equilibrium is a position where the net forces acting on a body cancels out and results in zero net force. Acceleration of a body is also zero when the velocity is moving with a constant velocity.

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

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

What happens to the body when it reaches equilibrium?

It depends upon the type of Equilibrium. Mechanical Equilibrium requires a Force balance on the body which will put it to rest physically. In the sense that, there won’t be any motion.

What is the meaning of equilibria of rigid body?

Equilibrium Of Rigid Body. If we have to define equilibrium the most simple definition would be it is a point where the net external force, as well as torque acting on the body about COM or any other point, is zero. But to be more specific for a rigid body equilibrium means both rotational as well as translational equilibrium.

When an object at rest must be in equilibrium?

By that criterion, an object at rest must be in equilibrium, since if the forces upon it were anything but balanced, it could not not remain at rest.

What is the definition of equilibrium in physics?

If we have to define equilibrium the most simple definition would be it is a point where the net external force, as well as torque acting on the body about COM or any other point, is zero. But to be more specific for a rigid body equilibrium means both rotational as well as translational equilibrium.
