## Can a physical quantity having both magnitude and direction be a vector?

A physical quality both magnitude and direction need not be considered a vector for e.g, despite having magnitude and direction, current is a scalar quantity.

## What is a value with magnitude and direction?

A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

## When two vectors have the same magnitude and direction is called?

The direction angle of a vector is a scalar. Two vectors are equal if and only if they have the same magnitudes and directions.

## Is force has both magnitude and direction?

(Introduction to Mechanics) vector quantities are quantities that possess both magnitude and direction. A force has both magnitude and direction, therefore: Force is a vector quantity; its units are newtons, N. Forces can cause motion; alternatively forces can act to keep (an) object(s) at rest.

## Is possession of magnitude and direction sufficient for calling a quantity a vector explain?

Answer. Answer: it is not necessary that a physical quantity that has magnitude and direction be a vector quantity. for a quantity which has magnitude and direction but does does not follow vector laws of addition is electric current.

## Which physical quantity has no direction?

Answer. Physical quantity which does not have direction is called Scaler Quantity. Physical quantity which has both direction and magnitude is called Vector Quantity.

## What is magnitude example?

Magnitude is defined as large in size or very important. An example of magnitude is the depth of the Grand Canyon. An example of magnitude is the size of the problem of world hunger. noun.

## Does magnitude have a sign?

The magnitude is always +ve or zero. A -ve sign in front of a vector indicates the same magnitude but in the opposite direction. The – sign is part of the direction rather than the magnitude.

## Does magnitude have direction?

Mathematicians and scientists call a quantity which depends on direction a vector quantity. Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction.

## Can you compare two vectors?

A vector quantity has two characteristics, a magnitude and a direction. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction. On this slide we show three examples in which two vectors are being compared. Vectors are usually denoted on figures by an arrow.

## What is the difference between magnitude and direction?

A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it. Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude.

## Are vectors equal?

Equal vectors are vectors that have the same magnitude and the same direction. Equal vectors may start at different positions. Note that when the vectors are equal, the directed line segments are parallel. If two vectors are equal then their vector columns are equal.

## What happens when 2 forces pull in the opposite direction?

A force is a push or a pull. What happens when two forces act in opposite directions? When two forces act in opposite directions, they combine by subtraction (same thing as adding a positive and negative number). If one force is greater than the other force, the overall force is in the direction of the greater force.

## What has magnitude as well as?

The strength of a force is expressed by its magnitude. The magnitude of a force is expressed in the SI unit of force called Newton. 1 Newton is the force which can make an object of 1 kilogram mass to move at a speed of 1 meter per second. The direction in which a force acts is also to be specified.

## What happens when two forces act on the same direction?

If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone.
