Explain why the total energy remains conserved during the oscillations?
In an oscillatory system, like a simple harmonic oscillator, the total energy is conserved because energy can only be converted between kinetic and potential energy as the system moves. The total mechanical energy (kinetic + potential) remains constant as the system oscillates back and forth. This conservation of energy is a fundamental principle of physics.
What is conserved during a reaction?
Both mass and charge
Which properties of a ball is conserved as it falls freely in a vacuum?
The mechanical energy of the ball is conserved as it falls freely in a vacuum, meaning the sum of its potential and kinetic energy remains constant. Additionally, the total momentum of the ball is conserved during its free fall.
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.
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.
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.
Is energy conserved only in exothermic reactions?
No, energy is conserved in all chemical reactions, not just exothermic ones. In an exothermic reaction, energy is released as heat to the surroundings, while in an endothermic reaction, energy is absorbed from the surroundings. The total energy of the system and surroundings remains constant during both types of reactions.
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.
Name a process in which momentum is conserved but kinetic energy is not conserved?
A collision between two objects where some of the kinetic energy is converted into other forms of energy, such as heat or sound. Momentum is conserved in such collisions because the total momentum before and after the collision remains constant, but kinetic energy is not conserved since it changes into other forms.
What is meant by saying that energy is conserved?
Saying that 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, but the total energy within the system remains the same.
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.
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
