BeauRelative motion in electronic navigation refers to the movement of a vessel in relation to fixed objects or other vessels. True motion, on the other hand, refers to the actual movement of the vessel independent of any external reference points. In electronic navigation, true motion is typically used for course plotting and position fixing, while relative motion is used for determining collision avoidance and situational awareness.

What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure.
The change in position of one object compared to the position of another?
Relative positioning refers to the change in position of one object relative to another object's position. It is a measurement of the displacement between the two objects and can be used to describe their motion in relation to each other. Tracking relative positioning is important in various fields, such as physics, engineering, and navigation, to understand the spatial relationship between objects.
What is the difference between gauge pressure and absolute pressure?
Gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the pressure measured relative to a perfect vacuum.
What is relative acceleration?
Relative acceleration refers to the difference in acceleration between two objects that are in motion relative to each other. It measures how their acceleration vectors are changing with respect to each other as they move. This concept is often used in the study of dynamics and motion in physics.
What is the difference between relative density and density, and how do they relate to each other?
Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of another substance, usually water. Relative density is also known as specific gravity. The relationship between relative density and density is that relative density is a comparison of densities, while density is an absolute measure of mass per unit volume.
