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.
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.
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.
Yes, momentum is conserved during an elastic collision.
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.

Mass is conserved. This means it remains constant.
Both mass and charge

Yes, momentum is conserved during an elastic collision.
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.
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.
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, 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.
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.
