(b) changing the direction of motion
(c) changing both the speed and direction of motion
(d) none of the above​

Answer 1

Answer:

Velocity of an object can be uniform or variable. It can be changed by changing the object's speed, direction of motion or both. When an object is moving along a straight line at a variable speed, the magnitude of an object with its rate of motion is described in terms of average velocity.
