moving along

The correct conversions are:

• km/h  $\div$  3.6 = m/s       and           m/s  $\times$  3.6 = km/h

• m/s  $\div$  3.6 = km/h          and          km/h  $\times$  3.6 = m/s

• m/s  $\div$  3.6 = km/h          and          km/h  $\div$  3.6 = m/s

• m/s  $\times$   3.6 = km/h          and          km/h   $\times$   3.6 = m/s

Which of the following is the correct unit of measurement of velocity?

• sec

• m/s

• m/h

• none of these

The difference between speed and velocity is that

• Speed tells how fast the object is moving along the ground covered, while velocity tells how fast the object has been displaced in a particular direction.

• Speed and velocity are always the same.

• Speed is with respect to time while velocity is with respect to speed.

• Velocity tells how fast the object is moving along the ground covered while speed tells how fast the object has been displaced in a particular direction.
