Write any two equations of motion for a body having uniform acceleration.
A girl running a race accelerates at $2.5\, m s ^{-2}$ for the first $4\, s$ of the race. How far does she travel in this time ?
Define acceleration. State a relationship connecting $u, v, a$ and $t$ for an accelerated motion. Give an example of a motion in which acceleration is uniform.
What is the relationship between the distance travelled and the time elapsed for motion with uniform velocity ?
What is the nature of the displacement$-$time graph of a body moving with constant velocity ?
