#speed of object is telling magnitude of it's velocity .
# it is a scaler quantity .
# it is used in everyday kinematics .

Answer 2

1.The distance travelled by an object per unit time

2.As the speedometer cable rotates, it turns the magnet at the same speed. The spinning magnet creates a fluctuating magnetic field inside the speed cup and, by the laws of electromagnetism, that means electric currents flow inside the cup as well.
