A conserved physical quantity is a property of a system that remains constant over time for an isolated system under certain conditions. This means that the total amount of that quantity within the system does not change, even as other processes take place. Examples include energy, momentum, and angular momentum in physics.
What else can I help you with?
What does it mean to say that a physical quantity is quantized or conserved?
To say that a physical quantity is quantized means that it can only take on discrete values or multiples of a fundamental unit. Conservation of a physical quantity means that the total amount of that quantity remains constant over time in a closed system, even if it may change forms.
When there is no external force acting on a body , which physical quantity is conserved?
Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
What is a conserved quantity?
A conserved quantity is a physical property of a system that remains constant over time, even as the system undergoes changes. Examples include energy, momentum, and angular momentum. The conservation of these quantities is a fundamental principle in physics and often allows us to make predictions about the behavior of a system.
When is angular momentum conserved in a physical system?
Angular momentum is conserved in a physical system when there are no external torques acting on the system.
What is the most significant similarity between conservation of energy and conservation of momentum?
in law of conservation of energy ENERGY IS CONSERVED and in law of conservation of momentum MOMENTUM IS CONSERVED. There's not similarity in these two laws. expect that in both laws , one quantity is conserved.
Which physical quantity is conserved when a planet revolves around the sun?
moment of inertia is conserved.

A quantity which is conserved in the collision of a car and a truck is?
Total momentum
When is angular momentum conserved in a physical system?
Angular momentum is conserved in a physical system when there are no external torques acting on the system.
What is the most significant similarity between conservation of energy and conservation of momentum?
in law of conservation of energy ENERGY IS CONSERVED and in law of conservation of momentum MOMENTUM IS CONSERVED. There's not similarity in these two laws. expect that in both laws , one quantity is conserved.
What are the two physical quantities that are not conserved?
Entropy and work (by non-conservative force ) are not conserved
When we say a quantity is conserved it means that what we start with is what we end up with?
Yes, the principle of conservation states that a specific quantity remains constant over time within a closed system. This means that the initial amount of the conserved quantity is equal to the final amount after any interactions or transformations occur.
What is conserved in physical changes?
Mass and energy
What is meant by unit of physical quantity?
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
Is distance a physical quantity?
Yes, it is a physical quantity (Fundamental)
