obtain the scalar components of velocity vector and acceleration vector ? full solution.
Answers
Answer:
In today’s world, various mathematical quantities depict the motion of objects into two categories. The quantity is as either a vector or a scalar quantity which distinguishes from one another by their difference and distinct definitions. Let’s study more about the scalars and vectors below.

Scalars and Vector Quantities
Scalar Quantities: The physical quantities which are specified with the magnitude or size alone are scalar quantities. For example, length, speed, work, mass, density, etc.
Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction. For example, displacement, force, torque, momentum, acceleration, velocity, etc.
Vectors
Comparison between Scalars and Vectors
Criteria Scalar Vector
Definition A scalar is a quantity with magnitude only. A vector is a quantity with the magnitude as well as direction.
Direction No direction Yes there is the direction
Specified by A number (Magnitude) and a Unit A number (magnitude), direction and a unit.
Represented by Quantity symbol Quantity symbol in bold or an arrow sign above
Example Mass and Temperature Velocity and Acceleration
Answer:
The two parts of a vector are known as components and describe the influence of that vector in a single direction. If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both a horizontal and a vertical component.
