Question

Acceleration is a vector quantity. Is force a vector quantity, too?

Answer 1

yes it is.
As you know
Force=Mass×Acceleration
Because Acceleration is a vector quantity
Hence Force also relieson direction
Force is vector

Answer 2

Answer:

Vector quantity

A  vector quantity is a quantity is a quantity that has both a magnitude and direction

Scalar quantity

A scalar quantity is a quantity that has only magnitude

Now ,

Acceleration

Acceleration is a vector quantity because it has magnitude and  direction is  both

Force

Force is a vector quantity because it has length and direction both .

We know that

Force = mass × acceleration
