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:
Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path (a trajectory) under the action of gravity only.
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 ...
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
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]
Example photo of the over-penetration of a fragmenting projectile. This class of projectile is designed to break apart on impact whilst being of a construction more akin to that of an expanding bullet. Fragmenting bullets are usually constructed like the hollow-point projectiles described above, but with deeper and larger cavities.
Another feature of projectile design that has been identified as having an effect on the unwanted limit cycle yaw motion is the chamfer at the base of the projectile. At the very base, or heel of a projectile or bullet, there is a 0.25 to 0.50 mm (0.01 to 0.02 in) chamfer, or radius.
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.
