Question

How can there be a quantity that has both magnitude and direction called?

Answer 1

Hint: 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.

Complete step by step solution:
A quantity which has both magnitude and direction is called vector quantities. Vector quantities are those quantities which have magnitude and direction.
Vector quantity is also specified by a number along with the direction and unit.
Examples of vector quantity that is speed , direction and displacement .
For example, a car is travelling at a speed of $5m/s$ in the northwest direction.
The mathematical quantities that are used to describe the motion of objects can be divided into two categories. The quantity is either a vector or a scalar. These two categories can be distinguished from one another by their distinct definitions.
Scalars are quantities that are fully described by a magnitude alone.
Vectors are quantities that are fully described by both a magnitude and a direction
Now let us know the real time example, in games, vectors are used to store positions directions and velocities. The position vector indicates how far the object is the velocity vector indicates how much time it will take or how much force we should give and the direction vector indicates in which we should apply the force.

Note: Representation for vector quantity - A number (magnitude), direction using unit cap or arrow at the top and unit. Vector Quantity symbol in bold and an arrow sign above
