Question

distinguish between speed and velocity answer

Answer 1

speed Is scalar quantity where as velocity is a vector quantity ...
speed has only magnitude where as velocity has both magnitude and direction..

Answer 2

Hi there !!!
Here's your answer

SPEED :
-)Speed is the measure of distance covered in a unit time .
-)It is a scalar quantity , meaning , there is no need to specify the direction of motion. The magnitude is enough to specify speed
-)Speed can never be negative. It is always positive.
-) Speed can also be defined as velocity which has no direction.
-) Speed can never decrease with time , meaning , for a moving body , it can never be zero.
-) The unit of speed is m/s or ms^-1

VELOCITY :
-) Velocity refers to speed along with direction specified.
-) It is a vector quantity, meaning , velocity needs both magnitude and direction to define it , otherwise, it's undefined.
-) Velocity can be negative , zero or even positive.
-) Velocity is a quantity which can decrease with time.
-) The unit of velocity is the same as speed , i.e, m/s.
