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.
When is kinetic energy conserved in a system?
Kinetic energy is conserved in a system when there are no external forces acting on the system, meaning that the total amount of kinetic energy remains constant.
What does it mean when energy is conserved and how does this principle impact the behavior of physical systems?
When energy is conserved, it means that the total amount of energy in a system remains constant over time. This principle impacts the behavior of physical systems by governing how energy is transferred and transformed within the system. It ensures that energy cannot be created or destroyed, only transferred between different forms, leading to predictable outcomes in the behavior of physical systems.
What evidence is there that energy is conserved in physical systems?
One key piece of evidence that energy is conserved in physical systems is the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed. This principle has been consistently observed and tested in various experiments and real-world applications, providing strong support for the idea that energy is conserved in all physical processes.
When is energy conserved?
Energy is conserved in a closed system where there is no net gain or loss of energy. This means that energy can change from one form to another, but the total amount of energy in the system remains constant.
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 conserved in physical changes?
Mass and energy
When is kinetic energy conserved in a system?
Kinetic energy is conserved in a system when there are no external forces acting on the system, meaning that the total amount of kinetic energy remains constant.

What is a conserved physical quantity?
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 does it mean to say energy is conserved within a system?
When an object is accelerated along a distance that requires energy. If the object is then slowed to a stop by a breaking system that gets back that energy then the energy is said to be conserved
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.
Can an objects mechanical energy change?
Yes, it can. For instance, if you have friction in the system mechanical energy of the system is not conserved.
What does the the phrase energy is conserved mean?
The phrase "energy is conserved" means that the total amount of energy in a closed system remains constant over time. Energy can change forms or be transferred between objects within the system, but the total energy within the system remains the same.
What type of system is neither the total mass nor the total energy conserved?
An open system is one where neither the total mass nor the total energy is conserved. In an open system, matter and energy can flow in and out of the system, leading to changes in both mass and energy within the system over time.
