Question

Does velocity decide the direction of motion of a body?​

Answer 1

$\huge{\boxed{\bf{Hola !}}}$

The acceleration of the body does not determine its direction of motion while velocity determines its direction of motion. Positive or negative sign of acceleration indicates if the velocity is increasing or decreasing whereas positive or negative sign of velocity indicates the direction of motion.

Answer 2

Answer:

Velocity determines the direction of motion

…acceleration determines how is velocity changing. A body can move in upward direction when the body is imparted a velocity in upward direction despite of the fact that acceleration is acting downward
