What does it mean to say momentum is conserved?
What does it mean to say momentum is conserved?
To say that electric charge is conserved is to say that electric charge?
To say that electric charge is conserved means that the total amount of electric charge in a closed system remains constant over time. This principle is a fundamental aspect of electromagnetism and is supported by experimental observations.
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.
When chemical reactions occur matters is conserved explain what that means?
No
Why does your ipod say do not disconnect while trying to charge?
it means do not disconnect the charger until ipod is charged
Is momentum conserved in elastic collisions?
Yes, momentum is conserved in elastic collisions. This means that the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.
When did albert Einstein invent e equals mc2?
In the beginning of the 20th century. He proposed mass-energy equivalence in 1905, and set out to mathematically express this. E = mc2 shows that energy can be converted into mass, and mass into energy. Thus, we no longer say that mass is conserved, or energy is conserved. But rather, we say that mass-energy is conserved.
What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
When is linear momentum conserved?
Linear momentum is conserved in a closed system when there are no external forces acting on it. This means that the total linear momentum of the system before an event is equal to the total linear momentum after the event.
Is electric charge conserved?
Yes, electric charge is conserved in any isolated system. This means that the total amount of electric charge remains constant before and after any interactions or reactions.
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.
Is mechanical energy always conserved Can you explain why or why not?
Mechanical energy is not always conserved. It can be converted into other forms of energy, such as heat or sound, through processes like friction or collisions. This means that the total amount of mechanical energy in a system may change over time, making it not always conserved.
