Question

difference between scalar -vector quantities .​

Answer 1

Answer:

difference between scalar and vector quantities....

1.Scalar.

these are physical quantities which are expressed only by their magnitude...

vector

these physical quantities required the magnitude as well as the direction to express them then only their meaning is complete...

2. scalar

example - mass, length, time, distance, density ,volume ,speed, temperature, work ,energy, power ,pressure.... etc..

vector

example- displacement, velocity, acceleration, Momentum, force, weight

etc...

$\large{\underline{\underline{\mathbf{Scalar\: quantities-}}}}$

⚫ These are completely specified by their magnitude only.

⚫ they change in of their magnitude only.

⚫these are added or subtracted by laws of ordinary algebra .

$\large{\underline{\underline{\mathbf{Vector\:quantities-}}}}$

⚫ These are completely specified by their magnitude as well as direction.

⚫ they change in either their magnitude or directions or both.

⚫ these are added or subtracted by laws of vector addition.
