What else can I help you with?
Within which type of system is neither the total mass nor the total energy conserved?
In an open system, neither total mass nor total energy is typically conserved. This is because open systems can exchange matter and energy with the surrounding environment, leading to changes in mass and energy within the system itself.
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.
Is it true that total energy is always conserved?
Yes, total energy is always conserved in a closed system, according to the law of conservation of energy. Energy can change forms within a system (e.g., potential energy to kinetic energy), but the total amount of energy remains constant.
When energy changes forms energy is always produced?
When energy changes forms, it is not always produced. In fact, energy is conserved in a system, meaning it can neither be created nor destroyed. So, when it changes forms, the total amount of energy remains constant.
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 is the law of conservation of enery?
It is, precisely, the statement that energy is conserved. To state it in different words: The total amount of energy (in a closed system) will neither increase nor decrease.
Is it true that total energy is always conserved?
Yes, total energy is always conserved in a closed system, according to the law of conservation of energy. Energy can change forms within a system (e.g., potential energy to kinetic energy), but the total amount of energy remains constant.

When energy changes forms, it is not always produced. In fact, energy is conserved in a system, meaning it can neither be created nor destroyed. So, when it changes forms, the total amount of energy remains constant.
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.
How is energy conserved in a closed system?
In a closed system, energy can neither be created nor destroyed, only transferred or transformed from one form to another. This principle is known as the law of conservation of energy. This means that the total energy within a closed system remains constant over time.
What type of system is the total mass conserved but not the total system energy?
An isolated system conserves total mass, but its total energy is not necessarily conserved. Energy can be exchanged between different forms (potential, kinetic, etc.) within the system, causing variations in total energy. Examples include chemical reactions or mechanical work where energy can be converted from one form to another.
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
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.
Which two properties of the system are conserved by the collision?
In an isolated system, both momentum and kinetic energy are conserved during a collision. Momentum is conserved because the total momentum before the collision is equal to the total momentum after the collision. Kinetic energy is conserved if the collision is perfectly elastic, meaning there is no energy lost to other forms (e.g., heat or sound).
How does energy is conserved in a transfermation of energy?
Energy is conserved in a transformation because it cannot be created or destroyed, only converted from one form to another. This means that the total amount of energy before and after a transformation remains constant. The law of conservation of energy states that energy can change from potential to kinetic, heat, light, sound, or other forms, but the total energy within a closed system remains the same.
