- Identify the following quantity as being either a scalar or a vector : 9.8 (m/s)/s down
(a. Scalar (b. Vector (c. Neither
- The given quantity is Vector quantity.
● Why 9.8 (m/s)/s is vector quantity ?
- 9.8 (m/s)/s or is quantity which denotes certain measurement of acceleration in downward direction.
● What are vector quantities ?
- Those measurements which has both magnitude & direction.
- It can either be negative or positive.
- Its examples are - Displacement, Force, Velocity & many more.
☆ Extra Information
- There also exists some other types of quantities : Scalar & Tensor Quantity
◇ Scalar Quantities are those measurements which has only magnitude but not direction. It can only exist as positive value but not negative or zero.
◇ Tensor Quantities are either scalar or vector quantity.
