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`
