What is a scalar and vector quantity ??​

the answer below me is correct

Explanation:

Scalar quantities

Scalar quantities only have magnitude (size).

For example, 11 m and 15 ms-1 are both scalar quantities.

Scalar quantities include:

distance

speed

time

power

energy

Scalar quantities change when their magnitude changes.

Vector quantities

Vector quantities have both magnitude and direction. For example, 11 m east and 15 ms-1 at 30° to the horizontal are both vector quantities.

Vector qualities include:

displacement

velocity

acceleration

force

weight

momentum

Vector quantities change when:

their magnitude changes

their direction changes

their magnitude and direction both change
