An achievement is a goal that has been reached.

An accomplishment is a job or project that has been completed.

Accomplishments

Accomplishment also involve change, but they present the events they refer to as bounded in time. They can be decomposed into two endpoints (the beginning and the culmination of the event) and a process part. Examples of accomplishment are "build a house", "run to the store".

Accomplishments can occur in the progressive. They do not occur with time-span adverbials, but do occur with time-frame adverbials.

• John is running to the store.

• John ran to the store in an hour/*for an hour.

Achievements

Achievement are like accomplishments lacking a process part. They denote punctual change. Examples of achievement predicates are "reach the top", "win the race", "find his glasses".

Great question! Creams are an aqueous oil/fat emulsion. This gives them a creamy consistency and are often "cream-colored" while lotions might be any color and need not be an emulsion- think Aloe Vera lotion for example. So a cream might also be called a lotion, while only creamy lotions could be called creams.

cream A viscous aqueous oil/fat emulsion with a medicament added, used to apply that medicament to the skin. (compare with ointment) You look really sunburnt; you should apply some cream.

lotion A low- to medium-viscosity topical preparation intended for application to unbroken skin.

Note that Wiktionary uses viscosity as another distinguishing characteristic. I'm not so sure that it works in all case- I've seen some pretty runny creams, and some thick lotions.
