Question

prove that acceleration is a vector quantity​

Answer 1

Explanation:

Acceleration is a vector quantity that is defined as the rate of change of velocity. If an object is said to be accelerating then it increases its velocity.we know that velocity is a vector quantity, thus acceleration is also a vector quantity. Acceleration is therefore some change in velocity by change in time.

Answer 2

Answer:

Vector quantity is a quantity which includes both magnitude as well as direction.

Acceleration can be either vector or scalar.

Depending on the situation if direction of acceleration is not relevant to you, then it is scalar, but if you consider that, it is a vector quantity.

To prove, we can see Newton's second law.

F = ma

Now, force is a vector .

Mass is scalar coz it does not have directions.

Now,

a = F /m

a = F × 1/m

So, acceleration is vector multiplied with scalar quantity.

When vector is multiplied by scalar, the product is also vector.

Hence proved, Acceleration is a vector quantity.
