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.
In physics, the monkey and hunter is a hypothetical scenario often used to illustrate the effect of gravity on projectile motion. [1] It can be presented as exercise problem or as a demonstration. The essentials of the problem are stated in many introductory guides to physics. [2] [3] In essence, the problem is as follows:
Interior ballistics can be considered in three time periods: [4] Lock time - the time from sear release until the primer is struck; Ignition time - the time from when the primer is struck until the projectile starts to move; Barrel time - the time from when the projectile starts to move until it exits the barrel.

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.
A projectile following a ballistic trajectory has both forward and vertical motion. Forward motion is slowed due to air resistance, and in point mass modeling the vertical motion is dependent on a combination of the elevation angle and gravity. Initially, the projectile is rising with respect to the line of sight or the horizontal sighting plane.
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.
The tautochrone problem is a special case of Abel's mechanical problem when () is a constant. Abel's solution begins with the principle of conservation of energy – since the particle is frictionless, and thus loses no energy to heat , its kinetic energy at any point is exactly equal to the difference in gravitational potential energy from its ...
The motion of a bouncing ball obeys projectile motion. [2] [3] Many forces act on a real ball, namely the gravitational force (F G), the drag force due to air resistance (F D), the Magnus force due to the ball's spin (F M), and the buoyant force (F B). In general, one has to use Newton's second law taking all forces into account to analyze the ...
