SUMMARY

Average velocity is a vector quantity, defined as displacement divided by time, while average speed is a scalar quantity, calculated as the total distance traveled divided by the time interval. The distinction lies in the fact that average velocity considers direction, allowing it to be positive or negative, whereas average speed does not. Understanding these differences is crucial for accurately interpreting motion in physics.

velocity and average speed are not the same. Please rephrase your question and tell us whether you feel each or both are scalar or vector quantities, and your reasoning behind your answer.
 
Average velocity is defined as displacement over time, or the change in position divided by time. Average speed, however, is equal to the distance traveled divided by the time interval of the motion. The two quantities are completely different. One is a vector and one a scalar; do you know why?
 
i think average velocity is a vector since it can be positive or negative right
