Why are position velocity and acceleration vectors and not scalars


Asked by admin @ in Physics viewed by 299 People


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?​

Answered by admin @



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.
