Question

give two differences between speed and velocity? question and answer

Answer 1

Speed is a scalar quantity,velocity is a vector quantity. Speed=distance x time,velocity=displacement/time

Answer 2

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

$\to$The rate of distance is called speed

$\to$It is scalar quantity

$\to$Speed is always positive

$\huge{ \star} \: \: \large\sf\fbox{ \fbox{Speed = \frac{distance}{time} }}$

$\to$The SI unit of speed is m/s

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

$\to$The rate of displacement is called velocity

$\to$It is vector quantity

$\to$Velocity can be positive , negative or zero

$\huge{ \star} \: \: \large\fbox{\fbox{ \sf Velocity = \frac{displacement}{time}} }$

$\to$The SI unit of velocity is m/s
