Your friend says his remote control car travels at a velocity of 1.5 m/s. What is wrong with that statement

    Hello jai. (lol we're using the same name) :p

    Anyway, I think the statement is wrong that it forgot to mention the direction where the car travels. Velocity is equal to displacement over time, which is a vector quantity, thus it shall be stated using magnitude and direction.
    In the statement above, it only says the magnitude (which is 1.5 m/s). It is not velocity, rather, it is just the speed.

    Note that speed is almost the same as velocity but does not require direction. It is defined by distance over time.

    Hope this helps~ :)
