Energy is neither used up nor destroyed, but it is converted into something else. In that way, it is conserved.
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
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.
In an inelastic collision, momentum is conserved. However, kinetic energy is not conserved as it is transferred to other forms such as heat, sound, or deformation energy.
Mechanical energy is not always conserved. It can be converted into other forms of energy such as heat, sound, or work, due to external forces like friction or air resistance acting on the system. In the absence of non-conservative forces, mechanical energy is conserved according to the law of conservation of energy.
In an inelastic collision, the total energy is not conserved because some of the kinetic energy is transformed into other forms of energy, such as heat or sound.
No. Total energy is always conserved, but not so mechanical energy.
no it's not cuz if there is friction energy wont be conserved

Not really, no.

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.
Mechanical energy is not always conserved. It can be converted into other forms of energy such as heat, sound, or work, due to external forces like friction or air resistance acting on the system. In the absence of non-conservative forces, mechanical energy is conserved according to the law of conservation of energy.
Energy is always conserved. When friction is present, the energy usually just turns into heat.
biomass can be conserved by turning it into usable fuels
In an inelastic collision, the total energy is not conserved because some of the kinetic energy is transformed into other forms of energy, such as heat or sound.
