Particle Under Constant Velocity

If the velocity of a particle is constant, its instantaneous velocity at any instant during a time interval is the same as the average velocity over the interval. Position–time graph for a particle under constant velocity. The value of the constant velocity is the slope of the line. `v_x = (x_f-x_i)/(∆t)` `=> x_f = x_i + v_x∆t`
