Question

Define speed? Write its formula and
units

Answer 1

$\Huge\textbf{Answer}$

$\huge\textbf{\pink{Speed}}$

▶️The distance travelled by a body per unit time is called speed.


▶️ Speed is scalar quantity


▶️The unit of speed is (metre/second) or m/s


▶️The formula of the speed is given below :-


.: Speed = Distance Travelled/Time taken


or


$\boxed{\bold{V = s / t}}$


where v = speed


s = distance travelled


t = time taken


Thanks


Have a colossal day ahead

Answer 2

Speed= The rate of change  in distance  with respect  to time is  called speed.

or,

Distance  traveled  in unit  time  is called  speed of  object .

Speed  is a scalar quantity. if  can   not  be  negative.

M.K.S Unit = metre/second

C.G.S Unit = cm/second

Dimensions  = [LT⁻¹]

Speed = Distance traveled/Time

$\text{if a body travels x distance in time t,then its speed}\\\;\\v=\frac{x}{t}\\\;\\If\;\;t\to0\\\;\\then,\\\;\\v=\frac{dx}{dt}\\\;\\\text{It is called instantaneous speed at time t}$
