A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.

Also called moment or moment of force. The tendency of a force to rotate an object about an axis, fulcrum, or pivot.

Material toughness ...
The upward or downward inclination of a natural or artificial surface (e.g. a hillside or a road), or the degree or nature of such an incline; a deviation from the perpendicular or horizontal direction (these directions generally being assigned with respect to the direction of the force of gravity).

A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. A force has both magnitude and direction, making it a vector quantity. Force density – Forging – Four-bar linkage – Four-stroke cycle – Four wheel drive –
For objects not in free-fall, the force of gravity is opposed by the reaction forces applied by their supports. For example, a person standing on the ground experiences zero net force, since a normal force (a reaction force) is exerted by the ground upward on the person that counterbalances his weight that is directed downward.
