kenimatics

Last week we discuss about displacement, velocity, distance and speed in our subject which is physics. This four topics are much related to each other it’s because of there applicability in the field of industry and in the simple rotation of life. Knowing them is so very useful in people who involve onboard for example; these four topics can apply to a simple problem application to a big industry which is included for counting as work.
Displacement (n Newtonian mechanics, specifies the position of a point in reference to an origin or to a previous position) which is applicable to a ship to move to a designated speed in a given distance and time, but can be change for some factors like sea waves, direction of the wind and emergency operations. Velocity is computed the ship to a given distance, speed and the direction. It is important to know a velocity of something moving tor a given direction it’s because it easily be located in any part of world and for any emergency to happen. Distance is a numerical description of how far apart objects are at any given moment in time. In physics distance may refer to a physical length, a period of time, or estimation based on other criteria (e.g. "two counties over"). These topics is very easy to understand to a idea of a crew or personnel onboard of there distance they covered. Speed is the rate of motion, or equivalently the rate of change in position, often expressed as distance traveled per unit of time. Speed calculates in the relation in sea or a area and the time and the other factors like the overall weight of the ship in the traveling at the sea. Speed can be change for some factors.

You seem to be confused with the plural and singular

(This four topics ARE?)

(These topics IS?)
