Question

difference between speed and velocity​

Answer 1

Answer:

• Speed is defined as distance travelled by a body per unit time
• Speed = distance travelled / time taken
• Speed is a scalar quantity
• Average speed cannot be zero

• Velocity is defined as the displacement of a body in unit time.
• Velocity = displacement / time
• Velocity is a vector quantity
• Average velocity can be zero

Answer 2

Answer:

Speed

It is defined as the distance travelled by an object per unit time.

Speed = Distance/Time

It is a scalar quantity.

Its S.I unit is m/s

Average speed = Total distance travelled/Total time

Average speed can't be zero.

Velocity

It is defined as the speed with direction. It is defined as the displacement per unit time.

Velocity = Displacement/Time

It is a vector quantity. Its S.I unit is m/s.

Average velocity = Initial + final velocity/ 2

Average velocity can be zero
