Question

which of the following quantities is vector
​

Answer 1

Answer:

For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination

Answer 2

Vector quantities are those that have magnitude as well as direction.

Explanation:

• Mathematical quantities that describes 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 only a magnitude.

• Vectors are quantities that are fully described by both a magnitude and a direction.

• Examples of vector quantity: Linear momentum , Acceleration , velocity, Displacement , Momentum , Angular velocity, Force , Electric field , Polarization etc.
• Vector quantities do not obey ordinary laws of algebra.
• Value of vector changes if either the direction or magnitude change or both change.
• Addition of vectors means finding the resultant of a number of vectors acting on a body.
• Vectors can be added geometrically but not algebraically.
