Question

Write the different between speed and velocity​

Answer 1

$\large \underline{\sf{Answer :}} \\ \\ \underline\textsf{ \dag \: \pink{Difference between Speed And Velocity}}$

$\sf{ \green{\underline{Speed : }}}$

Speed of a body is defined as the distance travelled per unit time.

$\dag \: \large \sf \red{ Speed = \frac{Distance \: Travelled}{ Time \: taken}}$

• ❍ SI unit of speed is meter per second m/s.
• ❍ Speed is a scalar quantity.
• ❍ speed of of a car is measured by an instrument called speedometer.

$\sf{ \green{\underline{Velocity : }}}$

Velocity of a body is the distance travelled by it per unit time in a given direction. It is represented by [v]

$\dag \: \sf \red{Velocity = \frac{Distance \: Travelled \: in \: a \: given \: direction}{ Time \: taken}}$

• ❍ SI unit of velocity is same as SI unit of speed which is m/s.
• ❍ Speed is a vector quantity.

Answer 2

Answer:

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
