Why is angular momentum conserved during a collision, while linear momentum is not conserved?
Angular momentum is conserved during a collision because the total amount of rotational motion remains constant due to the principle of conservation of angular momentum. This is because there are no external torques acting on the system during the collision. On the other hand, linear momentum is not conserved during a collision because external forces, such as friction or air resistance, can act on the objects involved, causing a change in their linear motion.
Explain how momentum is conserved when a car hits a bicycle?
When a car hits a bicycle, momentum is conserved because the total momentum of the system (car + bicycle) before the collision is equal to the total momentum after the collision. This means that the combined momentum of the car and bicycle remains constant despite the collision, with some of the momentum transferring between the two objects during the impact.
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 momentum conserved during an elastic collision?
Yes, momentum is conserved during an elastic collision.
Explain how mass and energy are conserved when evaporation?
During evaporation, the mass of the substance remains constant as the same number of atoms are present before and after the process. Energy conservation occurs through the transfer of energy from the surrounding environment to the liquid molecules, providing the energy required for them to escape into the gas phase.

What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
What is conserved during a reaction?
Both mass and charge

Is momentum conserved during an elastic collision?
Yes, momentum is conserved during an elastic collision.
During the interval of collision is the momentum conserved?
In an isolated system where no external forces are acting, momentum is conserved during the interval of collision. This means the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.
Explain how mass and energy are conserved when evaporation?
During evaporation, the mass of the substance remains constant as the same number of atoms are present before and after the process. Energy conservation occurs through the transfer of energy from the surrounding environment to the liquid molecules, providing the energy required for them to escape into the gas phase.
Why is mass conserved in chemical equation?
Mass is conserved in chemical reactions because the total number of atoms of each element before and after the reaction remains the same. This means that no atoms are created or destroyed during a chemical reaction, only rearranged into different molecules. This principle is known as the law of conservation of mass.
When two cueballs collide what happens to the momentum?
When two cueballs collide, momentum is conserved. This means that the total momentum before the collision is equal to the total momentum after the collision. The cueballs will transfer momentum between them during the collision, but the overall momentum of 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.
