Question

The quantity which determines the direction of motion of the body​

Answer 1

Answer:

Speed can be defined as the change of position of an object per unit time. Speed is a scalar quantity. Speed only gives us the magnitude, not direction. So, we can say that velocity and acceleration can determine the direction of the motion of a body.

Answer 2

Answer:

velocity

Explanation:

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.
