What else can I help you with?
What is conserved during a reaction?
Both mass and charge
Is kinetic energy conserved in an inelastic collision?
In an inelastic collision, kinetic energy is not conserved. Some of the kinetic energy is converted into other forms of energy, such as heat or sound, during the collision.
Is momentum conserved in an inelastic collision?
In an inelastic collision, momentum is not conserved. This is because some of the kinetic energy is converted into other forms of energy, such as heat or sound, during the collision.
Is momentum conserved in inelastic collisions?
In inelastic collisions, momentum is not conserved. This is because some of the kinetic energy is transformed into other forms of energy, such as heat or sound, during the collision.
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.
What is conserved during collisions?
Momentum and energy are conserved during collisions. Momentum is the product of an object's mass and velocity, while energy is the capacity to do work. In an isolated system, the total momentum and total energy before and after a collision will remain constant.
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.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
Which two properties of the system are conserved by the collision?
In an isolated system, both momentum and kinetic energy are conserved during a collision. Momentum is conserved because the total momentum before the collision is equal to the total momentum after the collision. Kinetic energy is conserved if the collision is perfectly elastic, meaning there is no energy lost to other forms (e.g., heat or sound).
Are there any common ways energy is changed from one form to another yet conserved?
Yes. Motors and generators exchange mechanical/electrical energy with heat as the conservation energy component. Heat and friction are the common ways energy is conserved as it is changed from one form of energy to another, e.g chemical to electrical by battery and heat.
Is energy lost during the transfer of energy levels?
In general, energy is conserved during energy transfers. However, some energy may be lost as heat due to inefficiencies in the transfer process.
Can energy be taken during a physical change?
No, energy cannot be taken during a physical change. Energy is always conserved, meaning it cannot be created or destroyed, only transferred or transformed from one form to another. During physical changes, such as melting or boiling, energy is absorbed or released, but the total amount of energy in the system remains the same.
