Minimum and terminal velocities in projectile motion

| Sumario: | The motion of a projectile with horizontal initial velocity V0, moving under the action of the gravitational field and a drug force is studied analytically. As it is well known, the projectile reaches a terminal velocity Vterm. There is a curious result concerning the minimum speed Vmin; it turns out that the minimum velocity is lower than the terminal one if V0 > Vterm and is lower than the initial one if V0 < Vterm. These results show that the velocity is not a monotonous function. If the initial speed is not horizontal, there is an angle range where the velocity shows the same behavior mentiones previously. Out of that range, the velocity is a monotonous function. These results come out from numerical simulations. |
