Question

estion: Why is it important to use vector quantities and not just scalar quantities to describe the motion of an object? Vector quantities deal with motion?​

Answer 1

Vector quantities are important in the study of motion. Some examples of vector quantities include force, velocity, acceleration, displacement, and momentum. The difference between a scalar and vector is that a vector quantity has a direction and a magnitude, while a scalar has only a magnitude. 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. A quantity which does not depend on direction is called a scalar quantity. Vector quantities have two characteristics, a magnitude and a direction. The resulting motion of the aircraft in terms of displacement, velocity, and acceleration are also vector quantities. A vector quantity is different to a scalar quantity because 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.

Step-by-step explanation:

Answer 2

As motion is described by physical variables that are described by Magnitude and Direction. Motion is determined by three variables: Position, Velocity and Acceleration.

Mathematically and physically speaking, Scalars are entities than can be represented only by Magnitude, whereas Vectors are entities that are represented both by Magnitude and Direction.

The Motion of the Object is described by three physical Variables: Position, Velocity and Acceleration, which are defined both by Magnitude and Direction.
