What does the term "conservation law" mean in physics?
Q: What does the term "conservation law" mean in physics?
A: A conservation law is a statement used in physics that says that the amount of something does not change in time.
Q: What are some examples of things that can be conserved according to conservation laws?
A: Some examples of things that can be conserved according to conservation laws are mass, charge, energy, and angular momentum.
Q: What is the "law of conservation of mass"?
A: The "law of conservation of mass" is the conservation law that says that the amount of mass is always conserved, even if it is changed into another form.
Q: Does the amount of mass change over time according to the "law of conservation of mass"?
A: No, the amount of mass does not change over time according to the "law of conservation of mass".
Q: If the mass of the universe could be measured right now, would its mass be known tomorrow?
A: Yes, if the mass of the universe could be measured right now, its mass would be known tomorrow because it will not change according to the "law of conservation of mass".
Q: Is energy conserved according to conservation laws?
A: Yes, energy can be conserved according to conservation laws.
Q: Can things that have to be calculated, like angular momentum, be conserved according to conservation laws?
A: Yes, things that have to be calculated, like angular momentum, can be conserved according to conservation laws.
