Projectile Motion. Projectile motion occurs when objects are fired at some initial velocity or dropped and move under the influence of gravity. One of the most important things to remember about projectile motion is that the effect of gravity is independent on the horizontal motion of the object.
Kinetic projectiles. A kinetic projectile can also be dropped from aircraft. This is applied by replacing the explosives of a regular bomb with a non-explosive material (e.g. concrete), for a precision hit with less collateral damage. A typical bomb has a mass of 900 kg and a speed of impact of 800 km/h (220 m/s).
Projectile motion has both vertical and horizontal motion. However, we will neglect air resistance in this case.

independent of the path taken between the initial and final point. An example of this is the force of gravity (weight): work by gravity is always equal to -mg times the change in height, ∆h. The amount of work done does not depend on how the object in question gets from one height to another, only on the final change in height.
