The distance travel by a body in the given time is called speed. For example a train covers a large distance at less time then the speed. Scalar quantity is the one which is described only with the magnitude. Where as, a vector quantity is .....

Uniform Velocity: -           If a body covers equal displacements in equal intervals of time, however small may be, the body is said to have uniform velocity. Its motion is said to be uniform. But be remember that .....

Let , a body is moving with initial velocity u m/s & uniform acceleration a, after time t seconds, it travelled  s distance and its final velocity is v m/s. Then, equations of motions are: i) v = u + at ii) s = ut + 1/2 at2 ii) v2  .....
