I understand the basics of speed and velocity, but I got a rather backhanded question on a recent test that I believe was marked incorrectly. Q: A baseball is thrown toward home plate. Is this a speed or a velocity? I said it was a speed, the ball could have been thrown from anywhere toward home plate. When I asked why it was a velocity, the response was that although the direction is unknown, it still has a direction. But then by that logic, all speeds would be velocities because they have to be traveling in a direction, even if it is not given. Did my teacher screw me over? Where am I going wrong?
