Answer 2

Answer:

Velocity of an object is equivalent to the rate of change of displacement. Where displacement is a vector quantity and is defined as the distance between the two positions of the object in a particular direction during a given time. Velocity is a vector quantity as it has both magnitude (speed) and direction.

Explanation:

The velocity of an object is the speed of an object moving in a definite direction.

The rate of change in the velocity of an object per unit time is referred as acceleration and the kind of motion is known as accelerated motion.

To compute the rate of change in velocity, or acceleration, of an object, the initial speed is subtracted from the final speed. This rate is then divided by the total length of the time period for the acceleration
