Explain with reason, which of the following graphs can possibly represent the motion of a particle observed in nature ?
If the average velocity of a body is equal to mean of its initial yelocity and final velocity, then the acceleration of the body is
What conclusion can you draw from the displacement$-$time graph of a body shown below ?
A car starts from rest and moves along the $x-$ axis with constant acceleration $5\, ms^{-2}$ for $8\,\sec $. If it then continues with constant velocity, what distance will the car cover in $12\,\sec $ since it started from the rest ?
Area under a $v -t$ graph represents a physical quantity which has the unit
