The aggregate vitality of a framework can be subdivided and characterized in different ways. For instance, traditional mechanics recognizes motor vitality, which is dictated by a protest's development through space, and potential vitality, which is a component of the position of a question inside a field. It might likewise be advantageous to recognize gravitational vitality, warm vitality, a few sorts of atomic vitality (which use possibilities from the atomic constrain and the feeble compel), electric vitality (from the electric field), and attractive vitality (from the attractive field), among others. A significant number of these orders cover; for example, warm vitality more often than not comprises somewhat of dynamic and incompletely of potential vitality.

A few sorts of vitality are a changing blend of both potential and dynamic vitality. An illustration is mechanical vitality which is the total of (normally plainly visible) active and potential vitality in a framework. Flexible vitality in materials is additionally reliant upon electrical potential vitality (among particles and atoms), as is concoction vitality, which is put away and discharged from a store of electrical potential vitality amongst electrons, and the atoms or nuclear cores that pull in them.[need citation to verify].The rundown is likewise not really entire. At whatever point physical researchers find that a specific marvel seems to disregard the law of vitality preservation, new structures are normally included that record for the error.

Warmth and work are uncommon cases in that they are not properties of frameworks, but rather are rather properties of procedures that exchange vitality. As a rule we can't quantify how much warmth or function are available in a protest, but instead just how much vitality is moved among articles in certain routes amid the event of a given procedure. Warmth and work are measured as positive or negative contingent upon which side of the exchange we see them from.

Potential energies are regularly measured as positive or negative contingent upon whether they are more noteworthy or not as much as the vitality of a predefined base state or design, for example, two interfacing bodies being interminably far separated. Wave energies, (for example, brilliant or sound vitality), active vitality, and rest vitality are each more prominent than or equivalent to zero since they are measured in contrast with a base condition of zero vitality: "no wave", "no movement", and "no dormancy", individually.

The qualifications between various types of vitality is not generally obvious. As Richard Feynman brings up:

These ideas of potential and motor vitality rely on upon a thought of length scale. For instance, one can talk about naturally visible potential and active vitality, which do exclude warm potential and dynamic vitality. Additionally what is called concoction potential vitality is a plainly visible idea, and nearer examination demonstrates that it is truly the whole of the potential and motor vitality on the nuclear and subatomic scale. Comparative comments apply to atomic "potential" vitality and most different types of vitality. This reliance on length scale is non-dangerous if the different length scales are decoupled, as is regularly the case ... be that as it may, disarray can emerge when distinctive length scales are coupled, for example when contact changes over plainly visible work into minuscule warm vitality.
