A motion simulator or motion platform is a mechanism that creates the feelings of being in a real motion environment. [1] In a simulator, the movement is synchronised with a visual display of the outside world (OTW) scene.
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.
The above way the body signals motion to the brain coincides very well with acceleration-onset cueing in a simulator. This is the reason why well-designed and properly set-up modern low-latency motion platforms in simulators work well for all aircraft from large transports to the low-g-force envelope of fighter aircraft.

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.
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.
The surface of the projectile also must be considered: a smooth projectile will face less air resistance than a rough-surfaced one, and irregularities on the surface of a projectile may change its trajectory if they create more drag on one side of the projectile than on the other. However, certain irregularities such as dimples on a golf ball ...
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]
