There are two more terms I need: "displacement" and "derived quantity". I know what displacement is but can't find a good definition for it, and I do not know what derived quantity is. If you can give me a definition or a link to a definition, that would be great. Thanks. :)

• Physical Science -

displacement is the difference of the initial position and final position.

derived quantity:

We know force is in newtons, mass in kilograms, and acceleration is in meters/sec^2

and we know that F=ma
so
1Newton=kg*m/s^2
the right is a "derived" quantity for the Newton

• Physical Science -

A quantity of steam (200g) at 110 c is considered, and the resulting water is frozen into ice at 0 c. how much heat was removed?
