Different units for measuring distance are:
1.for distances on earth miles , kilometer, meter
2. Between galaxies - light year.
Tit
The S.I. unit of distance is the metres, which is basically the distance between any two points.
Distance covered between two points in unit time. eg : distance between A and B /time taken =distance/time
a straight line distance between two points is known as length. its SI unit is meter (m).
In scientific measurements, however, length is the distance between two points. That distance might be the diameter of a hair or the distance from earth to the moon. The SI base unit of length is the meter, m. A baseball bat is about 1 m long. Metric rulers and meter-sticks are used to measure length. FIGURE 12 compares a meter and a yard.
distance is the separation between two points and scale is the type of unit you adpt to measure anything.
wavelength. It is the distance between two consecutive points that are in phase in a wave, such as between two high points or two low points. Wavelength is typically measured in meters or any other unit of length.
Miles.
kilometers
The S.I. unit of distance is the metres, which is basically the distance between any two points.
The modulus of the ratio of distance to displacement is always less than or equal to 1, as displacement is the shortest distance between two points. The unit for this ratio is dimensionless, as it is a pure number without units.
Displacement describes the distance between two points in space, and the direction of this distance relative to either of the two points. Velocity describes the rate of motion, per unit time, for any instant during the travel between these two points. ie. How fast an object traveled. Velocity must also describe the direction of travel relative to either of the two points.
