What is the Condition for the Conservation of Linear Momentum of a system?
A closed system
Why is the change of momentum zero in an isolated system?
In an isolated system, the total external forces acting on the system are zero. Since momentum is a vector quantity that depends on both the mass and velocity of an object, changes in momentum require an external force. Without any external force acting on the system, the total momentum remains constant, resulting in zero change in momentum.
What is 0 bar pressure?
A barometric pressure of zero is a vacuum.
What do you need in order to have a Force greater than zero acting on an object?
To have a Force greater than zero acting on an object, you need an external force to be applied to the object. Without this external force, the net force on the object will be zero, which means it will remain at rest or continue to move at a constant velocity due to Newton's First Law of Motion.
All forces are in balance and all forces are equal zero?
In a system where all forces are balanced, the net force on an object is zero, resulting in no acceleration. This state is known as equilibrium. It means that the object will remain at rest or move at a constant velocity unless acted upon by an external force.
Does an isolated system have net force acting on it?
Even if it does the net force acting on it should be zero. That's why it's called isolated.

Does a balanced force have a net force equal to the largest force?
A balanced force will have a net force that is equal to 0. A balanced force will have an opposing force of equal magnitude of the largest force.
What is 0 bar pressure?
A barometric pressure of zero is a vacuum.
Why doesn't the blood pressure within the arteries drop to zero?
The circulatory system is a closed system, it shouldn't be zero anywhere.
An object experiences a net zero external unbalanced force is it possible for the object to be travelling with a non-zero velocity?
Yes, it is possible for an object to be traveling with a non-zero velocity even if it is experiencing a net zero external unbalanced force. This is because the object may have inertia, which allows it to maintain its current velocity unless acted upon by an external force.

If the force polygon is not a closed figure what does it indicates?
That the forces sum to a non-zero resultant.
All forces are in balance and all forces are equal zero?
In a system where all forces are balanced, the net force on an object is zero, resulting in no acceleration. This state is known as equilibrium. It means that the object will remain at rest or move at a constant velocity unless acted upon by an external force.
What is the defined of force?
Force is an external effort and If the resultant of all force acting on a body is zero, then the forces are known as balanced force . Balanced forces do not change the speed.
Does a system with a net force of zero have to be in equilibrium?
Yes.
