In a campfire, the law of conservation of energy is conserved through the process of combustion. The potential energy stored in the wood is converted to heat and light energy as the wood burns. This transformation of energy is consistent with the principle that energy cannot be created or destroyed, only changed from one form to another.
What else can I help you with?
Which energy is always conserved?
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
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.
Which of the conservation law does not apply to an inelastic collision?
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
The rule stating that work output can never exceed work input is an application of the law of conservation of?
energy. This law states that energy cannot be created or destroyed, only transferred or transformed. The rule ensures that energy is conserved in a closed system.

Is it true that the law of conservation of energy stated that momentum is conserved in a collision?

In what situations does the law of conservation of energy not apply?
In general Conservation of Energy does not hold internal to a system, it only holds at the boundary of the system. This is where the limits of the system are. Internal to the system energy is not conserved. The situations where the Conservation does not apply is where the force is not zero or the first derivative of energy is not zero.
How are the law of conservation of mass and the law of conservation of energy similar?
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.
How are the law of conservation of energy and law of conservation of mass similar?
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.
The total amount of energy before and after a chemical reaction is the same .Thus energy is what?
Energy is conserved in a chemical reaction, meaning the total amount of energy before and after the reaction remains constant. This principle is known as the law of conservation of energy.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved.

Thus, conservation of momentum is often more useful for calculations involving collisions.
Why law of conservation of mass should better be called as law of conservation of mass and energy?
Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.
The rule stating that work output can never exceed work input is an application of the law of conservation of?
energy. This law states that energy cannot be created or destroyed, only transferred or transformed. The rule ensures that energy is conserved in a closed system.
Is energy always conserved in the universe?
Energy is always conserved in a closed system, according to the law of conservation of energy. However, in the universe as a whole, energy may not be conserved due to the expansion of space-time, which can lead to a net increase in energy.
