# How are vectors used in real life?

202122 ###### 2012-06-17 06:48:54

Vectors (as mathematical objects) are used wherever you have to calculate with both the size and direction of a parameter.

Some applications include:

• Moving objects (cars, boats, airplanes weather, etc) where you have a speed and a direction of motion.
• Forces

Vectors (as graphical objects) are used to draw images which do not loose their crisp sharpness when the image is magnified.

Vectors (in the medical sense) are the transmitters or carriers of a disease. E.g. the lice on the black rat was the vector fro the Bubonic Plague.

Sail boats. On board our boat we have an "apparent wind" speed/direction indicator. But truth tell, it's a constant mental evaluation of vector analysis: Wind from here, boat going in this direction, speed so & so, waves and current pushing the boat in another direction. Constant vector analysis (IN THE HEAD!).

Another real life situation: Bad guy runs and cop decides to shoot --- wind speed, movement of target, movement of shooter all vector analysis.

## Related Questions In real life unit vectors are used for directions, e.g east, north and up(zenith). The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level. Whenever and where ever location is important, unit vectors are a part of real life. Whenever directions are important in your real life, then unit vectors are important. If everything was confined to move along a straight line, then unit vectors would not be important. If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors. Any measurement in which the direction is relevant requires vectors. In real life unit vectors are used for directions, e.g east, north and up. The unit vector specifies the direction.

If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors. They are used in airplanes and in sailboats. Dropping a bullet and shooting a bullet at the same time. They will touch the ground at the same time because they are perpendicular vectors. Real world uses for vectors would be plotting courses for boats and planning the construction of roads  Vectors are used to denote or model directions. Trigonometry is used in the fields of design, music, navigation, cartography, manufacturing, physics, optics, projectile motion, and any other field which involves angles, fields, waves, harmonics, and vectors. flying planes, driving, measuring temperature, sailing "Positive" and "negative" is a concept that applies to real numbers, not to vectors. A vector (at least, the vectors commonly used in physics) has a length and a direction, and the way vectors are defined, this length (but not the vector itself) is always positive, or zero. how artificial chromosome are used as cloning vectors with example? Proportions are used in real life to determine prices of things. The law is used to add vectors to find the resultant of two or more vectors acting at a point. Believe it or not, school is a real life situation. If you are using it in school it real life for you. Anything that's moving involves vectors in some way. My favorite example is if you're walking in a given direction, and someone is approaching you perpendicularly, and you slightly speed up or slow down to avoid colliding with them. Vectors are one of the any variables used in the calculation of the speed of the ball. The term collinear is used to describe vectors which are scalar multiples of one another (they are parallel; can have different magnitudes in the same or opposite direction). The term coplanar is used to describe vectors in at least 3-space. Coplanar vectors are three or more vectors that lie in the same plane (any 2-D flat surface). Look at how it is done, then decide for yourself whether you consider this similar or not. Vectors are added by components - add the x-components and the y-components separately. The addition of the individual components is exactly the addition of real numbers (assuming the usual vectors used in physics - but more complicated types of "vectors" are also used in math). On the other hand, the magnitude of the sum of two vectors is usually less than the sum of the magnitudes of the vectors - unless they happen to point in exactly the same direction. For example, a vector 4 units in length plus a vector 3 units in length, at right angles, result in a vector 5 units of length, as is easy to deduce from Pythagoras's Law. However, once again, the components are added just like real numbers. If you are in school and are studying trig then you are using trig in real life. Cloning vectors are used to increase the number of copies of the cloned gene or to amplify a foreign gene. Expression vectors are used to increase the expression of the foreign gene product. In signals eigen values and eigen vectors are used in finding directions.... Signals are based on eigen vectors Two vectors are identical when all their components are identical. An alternative definition, for vectors used in physics, is that they are identical when both the magnitude and the direction are identical.  There are no vectors used in playing billiards or pool. The use of vectors oversimplifies the action of the balls in play and simply does not apply to the game. The physics of cue ball action relies more on rotational momentum than simple vectors, and ball to rail interaction is a complex mathematical problem that cannot be determined by simple vectors.
