Swell direction is typically measured in degrees, referring to the compass direction from which the swell is coming. For example, a swell coming from the north would have a swell direction of 0 degrees or 360 degrees.
The SI unit of luminous intensity is the candela.
The unit vector n that points in the direction of propagation is a vector with a magnitude of 1 that indicates the direction in which a wave or signal is moving.
Velocity is the change in position per unit time in a particular direction. It includes both the speed and the direction of an object's motion.
A unit vector is a vector with a magnitude of 1. It is often used to indicate direction without influencing the scale of a vector. Unit vectors are important in mathematics, physics, and engineering for simplifying calculations involving vectors.
The unit "m/s" in physics represents meters per second, which is used to measure velocity. Velocity is the rate at which an object changes its position in a specific direction over time. By using the unit "m/s," we can quantify how fast an object is moving in meters per second, providing a precise measurement of its speed and direction.
Swell height is the vertical distance (meters) between any swell crest and the succeeding swell wave trough.
That would be an angle; the SI unit for angle is the radian. However, that is not the unit that is commonly used in this case.
degree
There is no metric unit for direction: the old North, East, South and West serve.
In physics, distance is the unit which only has magnitude and not the directions.Hence,the term used for the measurement of distance and direction together is known as displacement.Distance is a scalar quantity.Distance + direction =Displacement .It is a vector quantity.
The SI unit of luminous intensity is the candela.
Pressure is defined as the force per unit area applied in a direction perpendicular to the surface. The standard unit of pressure is the pascal (Pa). This did not answer my question on how pressure is used.
The unit vector n that points in the direction of propagation is a vector with a magnitude of 1 that indicates the direction in which a wave or signal is moving.
Velocity is the change in position per unit time in a particular direction. It includes both the speed and the direction of an object's motion.
i is often used to denote the [imaginary] square root of -1. It can also be the unit vector in the horizontal direction.
a vector having unit magnitude and have a certain direction.
That's called a 'swab'.
