Question

which of the following best describes what a velocity vs. time graph shows? 1. only the distance traveled over time 2. speed and direction changes over time 3. only the acceleration of an object 4. only the speed of an object

Explanation:

Velocity is a vector quantity that includes speed and direction. A velocity - vs - time graph shows how the speed and direction (velocity) of an object change over time. Distance is not shown directly on a velocity - vs - time graph, acceleration is the slope of the graph but not the main thing it shows, and it is not just about speed as direction is also part of velocity.

Answer:

Speed and direction changes over time
