Question

what is the difference among average velocity, instantaneous velocity, and constant velocity? average velocity is the change in speed divided by time. instantaneous velocity is a changing variable. constant velocity is velocity that doesnt change. average velocity is the change in speed divided by time. instantaneous velocity is the velocity at a particular point in time. constant velocity is velocity that doesnt change. average velocity is the change in velocity (or displacement) divided by time. instantaneous velocity is the velocity at a particular point in time. constant velocity is unchanging velocity.

Explanation:

Average velocity is the total displacement (change in position) divided by the total time interval. Instantaneous velocity is the velocity of an object at a specific moment in time. Constant velocity means the speed and direction of an object do not change over time. The third - option correctly defines all three. The first option has an incorrect definition for average velocity as it should be change in displacement (not just speed) over time. The second option has a very vague description for instantaneous velocity.

Answer:

The third option: Average velocity is the change in velocity (or displacement) divided by time. Instantaneous velocity is the velocity at a particular point in time. Constant velocity is unchanging velocity.
