Energy can be transferred in many different ways; for instance, heat energy can be transferred by conduction, convection and radiation; energy can be transferred by electrical energy, or by sound, light, or by several other waves; a moving object (which has all sorts of types of energy) will change its position; etc.
No. Total energy is always conserved, but not so mechanical energy.
no it's not cuz if there is friction energy wont be 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
kinetic energy is transfered to electric energy
Not really, no.
Isn't it because some of the energy gets transfered to thermal energy?
You really should learn how to read and write before asking a question on WikiAnswers. Energy CAN be transfered, and furthermore energy DOES get transfered.
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.
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.
