Question

Which answer accurately describes the difference between speed and velocity?

Question 22 options:

Speed is the result of a change in direction. Velocity is the result of a change in acceleration.


Gravity affects speed. Gravity does not affect acceleration.


Speed only requires distance. Velocity requires direction.


Speed measures a change in inertia. Inertia remains the same in velocity.

Answer 1

Speed only requires distance. Velocity requires direction.

AS speed is scalar quantity and have only magnitude of distance covered .

But velocity is a vector quantity.To describe completely direction is also required alongwith magnitude of distance.
