Option A
Option B
Option C
Option D
Solution
| Vector quantities | scalar quantities |
| $(1)$ The physical quantities which require direction over and above their magnitude for their specification are called vector quantities. | $(1)$ The physical quantities which can be described bytheir magnitude only are called scalar quantities. |
| $(2)$ For Example : velocity, acceleration, force, weight, Displacement, momentum etc. | $(2)$ For Example : speed, mass, volume, size, temperature, amount of substance, power, work done, pressure, time etc. |
| $(3)$ While representing these quantities both magnitude and direction are to be stated. | $(3)$ While representing these quantities only its magnitude is required i.e., correct value with units. |
| $(4)$ These quantities can not be added algebraically. | $(4)$ These quantities are added or substracted algebraically. |
