Question

Which answer accurately describes the difference between speed and velocity?

Question 6 options:

Speed requires distance. Velocity requires direction.


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

Answer 1

speed requires distance velocity requires direction

Answer 2

Answer is: Speed requires distance. Velocity requires direction.

Velocity is equivalent to a specification of its speed and direction of motion, for example 200 km/h to the east.

Velocity is a physical vector quantity (measured in metres per second) and need magnitude and direction to define it, for example 200 metres per second east.

The speed (scalar quantity) of an object is the magnitude of its velocity.
