9th Class Science Time and Motion

      How will the equations of motion for an object moving with a uniform velocity change?

    Answer:

      We know that, the equations of uniformly accelerated motion are (i)                        (ii)                                (iii) where, u = Initial velocity v = Final velocity a = Acceleration t = Time and    s = Distance For an object moving with uniform velocity (velocity which is not changing with time), then acceleration a = 0. So, equations of motion will become (putting a = 0 in above equations) (i)                                  (ii)                             (iii)
