Question

which statement best supports the correct answer to part a? velocity - requires both speed and direction, and these examples only provide speed. can only describe objects that are accelerating, and these examples show constant motion. must be measured in meters per second, and these examples use different units. requires circular motion, and these examples describe linear motion.

Explanation:

Velocity is a vector quantity in physics. It requires both magnitude (speed) and direction to be fully described. The other options mis - represent aspects of velocity such as the need for circular motion, specific units, or the description of only accelerating or constant - motion objects.

Answer:

requires both speed and direction, and these examples only provide speed.
