What does it mean for a body to be in equilibrium and what are the conditions for a body to be in equilibrium?
A body to be in equilibrium means that the net forces ( resultant force ) acting on the body is "Zero".
This can occur in two cases :-
- When bodies at rest, e.g. , a parked car, a box at rest ... ( usually the downward weight balances the upward reactions ).
- When a body is moving with uniform speed in a straight line , e.g. , a car or a plane moving with uniform speed in a straight line ... ( usually the driving force of engine balances the force of friction or drag force ).
If a body is in equilibrium under the action of several parallel forces, it must satisfy two conditions :-
- The sum of the forces in one direction MUST equal the sum of the forces in the opposite direction.
- The principle of moments must apply . It states that : "The sum of anticlockwise moments about any point is equal to the sum of the clockwise moments about that point" .
( If there is no equilibrium , i.e. there is a resultant moment/force different from "Zero"; the resultant moment/force produces rotation/acceleration of the system or body. )

What condition or conditions must be met for a rigid body to be in equilibrium?
For a rigid body to be in equilibrium, two conditions must be met: the sum of all external forces acting on the body must be zero, and the sum of all external torques acting on the body must also be zero.
Which body is in equilibrium?
The human body is constantly working to maintain homeostasis, which is a state of equilibrium. This includes regulating temperature, pH levels, and other physiological processes to ensure optimal functioning. When the body is in equilibrium, it is able to effectively carry out its various functions and maintain stable internal conditions.
Why does the vibrating body move away from mean position?
When a vibrating body is displaced from its mean position, restoring forces act to bring it back to equilibrium. However, if the amplitude of vibration is large enough, the body may overshoot the mean position due to the inertia of its motion, causing it to oscillate around the equilibrium point.
What are the conditions for the complete equilibrium of a body?
For complete equilibrium of a body, the sum of all forces acting on the body must be zero (ΣF = 0) and the sum of all torques acting on the body about any point must also be zero (Στ = 0). This means that both the translational and rotational aspects of equilibrium are satisfied, ensuring that the body remains stationary and does not rotate.
How does the equilibrium relate to the body systems?
Equilibrium is the body's ability to maintain stability and balance. It is crucial for various body systems like the vestibular system, which helps in balance and spatial orientation, and the nervous system, which controls muscle movements. Disruptions in equilibrium can lead to issues such as dizziness, vertigo, and falls.

What is used to describe the conditions of a reaction at equilibrium?
The equilibrium constant (K) is used to describe the conditions of a reaction at equilibrium. It provides information about the relative concentrations of products and reactants at equilibrium.
What are the conditions of equilibrium when a number of parallel forces are acting on a body can a moving body be in equilibrium explain?
The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium. But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.
Why is it important to have the equilibrium conditions what does this equilibrium mean?
Equilibrium conditions are important because they represent a balance between forces, ensuring that a system remains stable and does not experience acceleration. Equilibrium means that the net force acting on an object is zero, resulting in no change in velocity or direction. This is crucial for determining the behavior and stability of objects or systems in physics.
What is the ability of the body to maintain equilibrium or steady state called?
The ability of the body to maintain equilibrium or steady state is called homeostasis. This process involves the regulation of various internal conditions, such as temperature, pH, and glucose levels, to ensure the body functions optimally.
Why a body cannot be in equilibrium due to single acting on it?
A body is in equilibrium when the force on it is zero, thus if a single force is on the body, the force must be zero or the body will not be equilibrium.
Why a body cannot be in equilibrium to single force acting on it?
A body is in equilibrium when the force on it is zero, thus if a single force is on the body, the force must be zero or the body will not be equilibrium.
Why does the vibrating body move away from mean position?
When a vibrating body is displaced from its mean position, restoring forces act to bring it back to equilibrium. However, if the amplitude of vibration is large enough, the body may overshoot the mean position due to the inertia of its motion, causing it to oscillate around the equilibrium point.
What is another biological word for equilibrium?
Another biological word for equilibrium is homeostasis. This term refers to the body's ability to maintain stable internal conditions despite external changes.
What is A process in the body that causes conditions to move away from the normal state?
Homeostasis is the body's process of maintaining internal stability and balance. When conditions deviate from the normal state, the body initiates responses to try to restore equilibrium.
What are the conditions for the complete equilibrium of a body?
For complete equilibrium of a body, the sum of all forces acting on the body must be zero (ΣF = 0) and the sum of all torques acting on the body about any point must also be zero (Στ = 0). This means that both the translational and rotational aspects of equilibrium are satisfied, ensuring that the body remains stationary and does not rotate.
