Question

Does acceleration tell us about the direction of motion

Answer 1

Acceleration does not actually tells us the direction of motion even though it is a vector quantity. Eg. a block is pushed against a surface having some friction. It will come to a stop after some time T. Since here, the block experiences retardation that is for any time between 0 and T, the direction of acceleration is opposite to the direction of it's motion. Hence, we can not say that acceleration is a definite parameter to analyse the motion of an object at that instant. But it can be used to determine how and in which direction the body will move in future.

Answer 2

Explanation:

yes its tells us about the direction
