Just like any \perpher vector, we can describe the velocity vector \vec{v} of an object in terms of its components. The x component of \vec{v}, which we call v_x, equals the x component of displacement (the change in the x coordinate during the time interval, \Delta{x} = x_2 - x_1) divided by the time interval \Delta{t} = t_2 - t_1; we define v_y, the y component of \vec{v}, in a similar way.
