| | Re: At what point(s) on a parabolic curve is a moving particle a rest? |
 | | In fact, if we are talking about the parabolic trajectory of a particle under the influence of gravity, and if frictional forces are ignored, the component of velocity along the X-axis will remain constant. |
| | Usually in physics when we talk about particles moving in a parabolic path, we are intending to describe the path of a particle given an initial velocity in a gravitational field. |
| | For instance, if one were to examine the parabolic trajectory in the polar coordinate system, the angular component would never become zero, but would approach zero at great distances from the center of the system. |
