Question

Why is acceleration a vector quantity?

Answer 1

Acceleration:

1. Acceleration is defined as the rate of change in velocity.
2. $Acceleration=\frac{Changeinvelocity}{time}$
3. If a physical quantity has both magnitude and direction, it is defined as a vector quantity.
4. Because velocity has both magnitude and direction, it is a vector quantity.
5. Therefore, Acceleration is also a vector quantity because it has both magnitude and direction.
