  2. Projectile motion - Wikipedia

    en.wikipedia.org/wiki/Projectile_motion

    The trajectory then generalizes (without air resistance) from a parabola to a Kepler-ellipse with one focus at the center of the Earth (shown in fig. 3). The projectile motion then follows Kepler's laws of planetary motion. The trajectory's parameters have to be adapted from the values of a uniform gravity field stated above.

  3. External ballistics - Wikipedia

    en.wikipedia.org/wiki/External_ballistics

    Projectile path values are determined by both the sight height, or the distance of the line of sight above the bore centerline, and the range at which the sights are zeroed, which in turn determines the elevation angle. A projectile following a ballistic trajectory has both forward and vertical motion.

  4. Ballistics - Wikipedia

    en.wikipedia.org/wiki/Ballistics

    A projectile is any object projected into space (empty or not) by the exertion of a force. Although any object in motion through space (for example a thrown baseball) is a projectile, the term most commonly refers to a weapon. [8] [9] Mathematical equations of motion are used to analyze projectile trajectory. [citation needed]

  5. Bouncing ball - Wikipedia

    en.wikipedia.org/wiki/Bouncing_ball

    The motion of a ball is generally described by projectile motion (which can be affected by gravity, drag, the Magnus effect, and buoyancy), while its impact is usually characterized through the coefficient of restitution (which can be affected by the nature of the ball, the nature of the impacting surface, the impact velocity, rotation, and ...

  6. Range of a projectile - Wikipedia

    en.wikipedia.org/wiki/Range_of_a_projectile

    Generally speaking, a projectile with greater volume faces greater air resistance, reducing the range of the projectile. (And see Trajectory of a projectile.) Air resistance drag can be modified by the projectile shape: a tall and wide, but short projectile will face greater air resistance than a low and narrow, but long, projectile of the same ...

    en.wikipedia.org/wiki/Projectile

    In projectile motion the most important force applied to the ‘projectile’ is the propelling force, in this case the propelling forces are the muscles that act upon the ball to make it move, and the stronger the force applied, the more propelling force, which means the projectile (the ball) will travel farther. See pitching, bowling.

    If your goal is to pay off your home sooner, consider making an extra monthly home payment. Or think about making larger monthly payments throughout the year. If you can, try biweekly payments or ...

  9. Trajectory - Wikipedia

    en.wikipedia.org/wiki/Trajectory

    A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a ...
