Question

the rate of change of velocity per unit time is called as
(a)speed
(b)acceleration ​

Answer 1

Answer:

(b) acceleration

Explanation:

the rate of change of velocity bper unit is called as acceleration

Answer 2

The rate of change of velocity per unit time is known as acceleration. (Option B)

• Acceleration is the rate of change in velocity of an object per unit time, and accelerated motion is the type of motion. Acceleration, like velocity, is a vector with both magnitude and direction.
• The pace at which distance changes with time is referred to as speed. To determine an object's speed, we must first know how far it has traveled and how long it took to get there.
• As a result, option B is the proper response to the question.
