Which answer would score higher? Not sure where to start? Explain this Answer A Speed is a scalar, so its unchanged value only states how fast the carriage moves. Clockwise motion is eastwards at the northernmost point and westwards at the southernmost point. Velocity is a vector, so these opposite directions give different velocities. Answer B Speed is a scalar, so its unchanged value only states how fast the carriage moves. Velocity is a vector, so the carriage has different velocities at the northernmost and southernmost points despite moving at the same speed.
