Question

Is speed a vector quantity? Give reason.​

Answer 1

Answer:

$\large\boxed{\sf{No}}$

Explanation:

Speed is a scalar quantity.

Speed is the distance travelled per unit time.

Also, we can write as,

Speed = Distance/Time

It's SI unit is m/s.

It depends on the total path length covered by any particle, and that total path length is called the distance covered.

Distance can not ever be negative.

It can be zero or positive only.

To convert speed from Km/h into m/s , just multiply the term with 5/18.

To convert the speed from m/s into )km/h, just multiply the term with 18/5
