Question :

acceleration is a vector quantity what indicates that it is. (a) +ve (b)-ve (c)zero (d) both +ve &-ve.

Concepts :

Scalar Quantities : The quantities that can described by only the magnitude are called scalar quantities.

Vector quantities : The quantities that can described with the help of magnitude as well as direction is called vector quantities.

Solution :

Acceleration is a vector quantity

Hence it can be +ve as well as -ve.

The -ve acceleration is specifically called retardation.

Option :

The correct option is option D)
