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.

How does a vector represents distance and direction?
A vector is like an arrow. It points in the relevant direction and its length is a measure of the distance.
What is Two km south is a measure of?
2 km is a distance; south is a direction.
What is spatial depth?
it goes in both direction to measure the distance of something from top to bottom.
Ways to measure wind direction without a wind vane?
Propel an object into the air and measure the direction and distance it goes in. Or use the good old lick your finger and point it in the air until you find the direction of wind.
What is an object's height a measure of?
An object's height is the measure of the distance between its lowest point and its highest point expressed in linear units.
A measure of motion defined as distance traveled per unit of time?
Speed is equal to distance divided by time Algebraically s = d/t To do this mechanically, you need a clock/watch to measure the time. and some form of distance measure e.g. ruler, or mile posts. In a motor car you have the speedometer and odometer. They measure the speed at any given moment, and the distance travelled.
How do you measure constant velocity?
Constant velocity is, well, constant. To measure it, measure the displacement through a given or fixed period of time. You'll have distance and time. Distance per unit time is speed. Distance per unit time (speed) with a direction vector is velocity. Velocity is speed in a given direction. If something is moving at constant velocity, it is moving at a constant speed in one direction. No changes in speed (no positive or negative acceleration, or, said another way, no acceleration at all), and no change in direction or heading.
What is a synonym for velocity?
There is no synonym to velocity. there is no directionality in velocity. speed is a measure of rotation around a center expressed in revolutions per unit of time. Velocity is a measure of distance in units of time with no direction. Vectors indicate direction.
What measures the rate of change in velocity?
Police measur speed with a radar gun. It uses the Doppler effect to find speed. You can measure distance traveled and use a stopwatch to measure speed yourself. You asked about velocity, however. Velocity is the combination of speed and direction. To measure velocity, you have to track the direction of travel. For that, either a compass, a chart or some other measure.
How does distance and displacement differ?
Distance is a scalarwithout direction and displacement is a vector with distance and direction.
What weighs 30 inches?
Nothing.Inches are a measure of distance, not weight.Nothing.Inches are a measure of distance, not weight.Nothing.Inches are a measure of distance, not weight.Nothing.Inches are a measure of distance, not weight.
What are the difference between speed and distance?
Speed is a measure of the RATE at which a Distance is traversed. The units of distance would be Feet, inches, meters, etc. The units of Speed are Feet/Sec, inches/hour, meters/month, etc. When you speak of VELOCITY, you are adding the additional measure of DIRECTION. Direction may be expressed in Angular Degrees, Left or right, North, South, East, West, etc.
