The word depreciation has different meanings in different contexts, so it is important to understand the context in which it is used. Generally, it is a decrease in the value of an asset over time due to wear and tear, obsolescence or other factors. For example, when a car is purchased, its value depreciates over time due to use and tear.

Composite life is used in the context of machine parts, where it is a measure of a part’s expected life before it requires maintenance or must be replaced. It is the sum of the estimated life of the individual components of the machine part.

Finally, life is used to describe the period of time when an asset is expected to remain in service before it must be replaced or repaired. This can refer to machinery, buildings and other assets. For example, a building may have a life of 40 years before it needs to be repaired or replaced.

In conclusion, depreciation, composite life and life are three terms that are important to understand in terms of the lifespan of assets. Depreciation refers to a decrease in an asset’s value over time, composite life is the sum of the estimated life of a part’s individual components and life is the period of time when an asset is expected to remain in service before it must be replaced or repaired.
