Question

Write two differences between speed and velocity.

Answer 1

$Speed:$

• Speed is how fast an object is moving. It is calculated by the distance covered per unit of time.
• Speed has only magnitude, i.e. it is a scalar quantity.

$Velocity:$

• Velocity is the rate at which an object changes position in a certain direction. It is calculated by the displacement per unit of time in a certain direction.
• Velocity has a direction as well as magnitude, i.e. it is a vector quantity.
