What else can I help you with?
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
Mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
In a collision what is conserved?
In a collision, the total momentum of the system is conserved if no external forces act on the system. This means that the total momentum before the collision is equal to the total momentum after the collision.
How energy conserved in a transformation?
A energy can be changed or transformed. When you rub your hands together,your hands become warm. Mechanical energy due to motion is changed into heat energy

In a nuclear reaction WHAT does not have to be conserved?
While overall ENERGY has to be conserved, MASS does not. In a nuclear reaction mass can be converted into energy so the mass of the products may be less than the mass of the reactants. The difference in mass is converted into energy as Einstein's equation describes (E=MC squared). In a chemical reaction MASS has to be conserved.
What does it mean when a collision is elastic and how does it differ from an inelastic collision?
In an elastic collision, kinetic energy is conserved and the objects bounce off each other without losing energy. In an inelastic collision, kinetic energy is not conserved and some energy is lost as the objects stick together or deform.
Is rock conserved in the same sense that energy is conserved?
Not really, no.
What is energy defined as?
I suggest you read the Wikipedia article on "energy". There is really no definition of "energy" that's short, easy to understand, and accurate; the reason for this is that "energy" is a fairly complex concept. You might say that it's a magnitude in physics that is conserved - you can't increase or decrease the total amount of energy. However, note that there are several other magnitudes in physics that are also conserved.

Is energy always conserved in the universe?
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.
