hello,
could you please tell me if the velocity is the average speed a vector or scalar quantity?

thanks a lot

thanks a lotvelocity 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
