Question

Which BEST describes the difference between speed and velocity? A) Velocity is instantaneous. B) Speed is a vector quantity. C) Speed includes rate of change and direction. D) Velocity includes rate of change and direction.

Answer 1

the answer is....        d!

Answer 2

Answer:

Option (d) is correct.

Explanation:

Speed is defined as the ratio of distance traveled to the time taken.

As distance is scalar quantity, time is also scalar, so the speed is a scalar quantity.

Velocity is defined as the ratio of change in displacement to the time take.

Here displacement is a vector quantity, so velocity is a vector quantity.

So, velocity includes the rate of change of displacement and the direction.
