Vector
, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude.
What quantity has both magnitude and no 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.
Which of the following quantities does not have both magnitude and direction?
Scalar
quantity is having only magnitude but no direction. Vector quantity is the physical quantity having both magnitude and direction. 2.
Does power have both magnitude and direction?
Examples of such quantities include distance, displacement, speed, velocity, acceleration, force, mass, momentum, energy, work, power, etc. …
A vector quantity
is a quantity that is fully described by both magnitude and direction.
Which quantities have both a magnitude and direction answers com?
A quantity which has both magnitude and direction is called_________ Answer: A quantity which has both magnitude and direction is called
vector quantities
.
Does mass has both magnitude and direction?
Weight is a force which is a vector and has
a magnitude and direction
. Mass is a scalar. Weight and mass are related to one another, but they are not the same quantity.
How do you find magnitude and direction?
MAGNITUDE AND DIRECTION OF A VECTOR
Given a position vector →v=⟨a,b⟩,the magnitude is found by
|v|=√a2+b2
. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application.
Which if the following is a physical quantity that has a magnitude but no direction?
A scalar
is a physical quantity that has magnitude but no direction.
What has both size and direction?
A quantity that is specified by both size and direction is
a vector
. Displacement includes both a size and direction and is an example of a vector. However, distance is a physical quantity that does not include a direction and isn't a vector. … Velocity is a vector that has size and direction.
Which has only magnitude no direction?
A scalar
is any quantity that has a magnitude, but no direction.
How do you find the direction of two vectors?
The direction of a vector is the measure of the angle it makes with a horizontal line .
tanθ=y2 − y1x2 − x1
, where (x1,y1) is the initial point and (x2,y2) is the terminal point. Example 2: Find the direction of the vector →PQ whose initial point P is at (2,3) and end point is at Q is at (5,8) .
Is current have direction?
Current has a
direction
. … By convention, the electric current direction is the direction which positive charge would move. In wires, the actual charge carriers are negatively charged electrons. Nonetheless, the convention used for the direction of current is based on the direction which positive charges would move.
Why distance has no direction?
Distance traveled is the total length of the path traveled between two positions. Distance traveled is not a vector. It has no direction and, thus,
no negative sign
. … It is important to note that the distance traveled does not have to equal the magnitude of the displacement (i.e., distance between the two points).
Which has magnitude as well as direction?
Force
has a well-defined magnitude as well as direction.
Why is time a scalar?
Scalar quantities have only magnitude; vector quantities have both magnitude and direction.
Time is completely separated from direction
; it is a scalar. It has only magnitude, no direction. … Time is a scalar.
