# Objects in dynamic equilibrium

• samona
In summary, an object in dynamic equilibrium remains in a constant position and velocity and experiences no acceleration. This requires a net force of zero and can occur when the object is at rest or moving at a constant velocity. This is different from static equilibrium, where the object is completely at rest, and may have unbalanced forces present. An object can also be in dynamic equilibrium while undergoing rotational motion if the angular velocity remains constant and the net torque is zero. However, dynamic equilibrium can be disrupted by changes in forces, such as mass, velocity, or external factors like air resistance and friction.

What makes objects in dynamic equilibrium move? It can't be gravity because then it would only be one force and if an object is under the influence of one force, then it cannot be in equilibrium. Any help would be appreciated.

Some external things change, and this changes the dynamic equilibrium.

what i meant is what is the reason that moving objects continue moving?

## What is an object in dynamic equilibrium?

An object in dynamic equilibrium is a state in which the object's position and velocity remain constant over time. This means that the object is not accelerating, and the forces acting on it are balanced.

## What are the conditions for an object to be in dynamic equilibrium?

An object can be in dynamic equilibrium if the net force acting on it is zero, and if the object's acceleration is also zero. This means that the object is either at rest or moving at a constant velocity.

## How is dynamic equilibrium different from static equilibrium?

In dynamic equilibrium, the object is experiencing motion at a constant velocity, whereas in static equilibrium, the object is completely at rest. Additionally, in dynamic equilibrium, the forces acting on the object are balanced, while in static equilibrium, there may be unbalanced forces present.

## Can an object be in dynamic equilibrium while undergoing rotational motion?

Yes, an object can be in dynamic equilibrium while undergoing rotational motion. This occurs when the object's angular velocity remains constant, and the net torque acting on the object is zero.

## What factors can disrupt dynamic equilibrium?

Dynamic equilibrium can be disrupted by any changes in the forces acting on the object. This can include changes in the object's mass, velocity, or the forces acting on it. Other factors such as air resistance and friction can also disrupt dynamic equilibrium.
