  2. Internal ballistics - Wikipedia

    en.wikipedia.org/wiki/Internal_ballistics

    Some energy is lost in deforming the projectile and causing it to spin. There are also frictional losses between the projectile and the barrel. The projectile, as it travels down the barrel, compresses the air in front of it, which adds resistance to its forward motion. [1] The breech and the barrel must resist the high-pressure gases without ...

  3. Projectile motion - Wikipedia

    en.wikipedia.org/wiki/Projectile_motion

    In projectile motion, the horizontal motion and the vertical motion are independent of each other; that is, neither motion affects the other. This is the principle of compound motion established by Galileo in 1638, [ 1 ] and used by him to prove the parabolic form of projectile motion.

  4. Range of a projectile - Wikipedia

    en.wikipedia.org/wiki/Range_of_a_projectile

    The path of this projectile launched from a height y 0 has a range d.. In physics, a projectile launched with specific initial conditions will have a range.It may be more predictable assuming a flat Earth with a uniform gravity field, and no air resistance.

  6. Tsiolkovsky rocket equation - Wikipedia

    en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

    A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

  7. Ballistics - Wikipedia

    A sling is a projectile weapon typically used to throw a blunt projectile such as a stone, clay or lead "sling-bullet". A sling has a small cradle or pouch in the middle of two lengths of cord. The sling stone is placed in the pouch. The middle finger or thumb is placed through a loop on the end of one cord, and a tab at the end of the other ...

  8. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    Galileo deduced the equation s = ⁠ 1 / 2 ⁠ gt 2 in his work geometrically, [4] using the Merton rule, now known as a special case of one of the equations of kinematics. Galileo was the first to show that the path of a projectile is a parabola. Galileo had an understanding of centrifugal force and gave a correct definition of momentum. This ...

  9. Trajectory - Wikipedia

    en.wikipedia.org/wiki/Trajectory

    The mass might be a projectile or a satellite. [1] For example, it can be an orbit — the path of a planet , asteroid , or comet as it travels around a central mass . In control theory , a trajectory is a time-ordered set of states of a dynamical system (see e.g. Poincaré map ).
