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 does it mean when the net charge is conserved in a closed system?
When the net charge is conserved in a closed system, it means that the total charge within the system remains constant over time. This implies that no charge is lost or gained within the system as a whole, but it can be redistributed among the particles present.
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.
Is potential energy conserved or not measurable?
It is not conserved. Total energy is conserved, but specific types of energy are usually not conserved. Not sure what you mean by "measurable" - potential energy is usually calculated, on the basis of other quantities. For example, in the case of gravitational potential energy, PE = mgh (mass x gravity x height), all of which can be measured.
When a pendulum swings the size of the swing gradually reduces with time until the pendulum stops explain how this can be possible if energy is conserved?
Energy is conserved in an isolated system, meaning since energy cannot be created or destroyed, the amount of energy in the system is the same. The point is, what is the 'system' in a certain scenario. Even if the pendulum was in an isolated room, that doesn't mean the pendulum will swing forever, because energy is constsntly lost to the environment, due to the friction with the air. But while energy is lost from the pendulum, energy is gained by the surrounding air molecules (also isolated), and thus energy in the system is conserved. Eventually the pendulum's kinetic energy will be zero, having lost too much to be able to make it move.

What does it mean to say momentum is conserved?
What does it mean to say momentum is conserved?
What does it mean when a collision is elastic and how does it differ from an inelastic collision?
In an elastic collision, kinetic energy is conserved and the objects bounce off each other without losing energy. In an inelastic collision, kinetic energy is not conserved and some energy is lost as the objects stick together or deform.
What does it mean for a quatity to be conserved?
For a quantity to be conserved means that its total amount remains constant over time, even though it can change form or location. This conservation principle is often found in physics, where quantities like mass, energy, momentum, and electric charge are conserved. Mathematically, conservation laws are expressed as equations that describe the relationship between the initial and final states of a system.
How are energy and mass conserved by living systems?
Not quite sure what you mean; let's just say that living systems don't require any extraordinary efforts to conserve energy and mass, because that's what they do naturally, i.e., "be conserved". There is no known way to violate conservation of energy or mass.
Does Einstein's famous equation suggests that mass and energy together are conserved or not?
Einstein wrote more than one 'famous equation', but the one you mean is e=mc2 . This shows that mass may be converted to energy, or energy to mass, under the right conditions. c2 gives the rate of exchange between the two. Since c (the speed of light) is a large number, its square implies a ruinous exchange rate if you want to create mass, and a good deal if you can turn mass into energy. In any closed system you can begin by measuring the quantities of energy and mass, then use the equation to convert mass to energy, or vice versa. Then, whatever you do in your closed system, the total mass equivalent, or energy equivalent, will remain what it was before. In short, mass-energy is conserved.
Need an explanation why kinetic energy is always conserved during elastic collision what is meant by conserved?
In this context "conserved" means the total kinetic energy of all the objects is the same after the collision as before the collision. Note, the TOTAL is the same but the individual kinetic energies of each object may be different before and after. When two or more objects are about to collide they have a certain total kinetic energy. It is common that during the collision some of the kinetic energy is transformed into heat. So after the collision the total kinetic energy is less then before the collision. This is a non-elastic collision. There are some collisions, however, in which none of the kinetic energy is changed to heat. These are called ELASTIC collisions. So the total kinetic energy doesn't change, or is "conserved". There is another possible non-elastic collision. If during the collision there is an explosion, then its possible for the objects to have a larger total kinetic energy after the collision as they aquire some of the explosive energy. Finally note, that in all collisions the TOTAL vector momentum is the same just before and just after the collision. So in a collision momentum is always conserved.
What does conserved mean?
Conserved means to preserve or protect something, such as resources, energy, or natural habitats, in order to prevent depletion or destruction. Conservation efforts aim to maintain the integrity and balance of ecosystems and resources for future generations.
