What is vector in physics?

Answer 1

Definition of a vector. A vector is an object that has each a magnitude and a direction. Geometrically, we can photograph a vector as a directed line segment, whose size is the magnitude of the vector and with an arrow indicating the direction. The course of the vector is from its tail to its head

Answer 2

In physics, a vector is a quantity that has both magnitude and direction. It is represented with an arrow pointing in the direction of the quantity and its length representing the magnitude. Vectors are used to describe physical quantities such as force, velocity, and acceleration.

Answer 3

Any element of a vector space

• Euclidean vector, a geometric entity endowed with both length and direction, an element of a Euclidean vector space
• Coordinate vector, in linear algebra, an explicit representation of an element of any abstract vector space
• Probability vector, in statistics, a vector with non-negative entries that add up to one
• Row vector or column vector, a one-dimensional matrix often representing the solution of a system of linear equations
• Tuple, an ordered list of numbers, sometimes used to represent a vector
• The vector part of a quaternion, a term used in 19th century mathematical literature on quaternions.

this is by mehansa different user

it acually simpler than that vector is something with a value of a direction

Answer 4

A vector is a physical quantity which has not only magnitude, but also a direction.

For example: Weight is a vector quantity. Its magnitude is how much a certain body (maybe yours?) weighs due to the pull of Earth's gravity. Its direction is toward Earth's center of mass.

Mass is not a vector. It is a scalar quantity. Your mass has no inherent direction. Your weight does once the Earth acts on it.

Here is another example: If you are driving fast from Georgia to Florida, your speed might be 80 mph (scalar, magnitude only.) If, for the benefit of your physics professor, you added the direction to your speed, you would have velocity. 80 mph SOUTH. Velocity is one example of a vector.

Answer 5

It is a quantity that cannot be adequately described as a scalar... it has not only a magnitude, but a direction as well.
Force Displacement

Answer 6

You might define vector by stating that a vector is a quantity with a direction and a magnitute. The vector helps to determine a position in space and is used in mathematics.

Answer 7

In Physics a vector is a number with a direction.

Answer 8

a quantity with magnitude and a direction.
