On the other hand, E-beam sterilization can be harmful to products containing batteries or electronic components. It can also degrade rubber and polypropylene, but these materials now come in grades that are E-beam compatible, Wilson notes.
A trajectory is the path of an object through space, or the path of life that a person chooses. The prefix tra- is short for trans-, which means across (think transport and transit) and the ject comes from jacere, which means throw and is also the root of the word jet.
Projectile motion is a form of motion experienced by an object or particle that is thrown near the Earth's surface and moves along a curved path under the action of gravity only. This curved path was shown by Galileo to be a parabola. The study of such motions is called ballistics, and such a trajectory is a ballistic trajectory. The only force of significance that acts on the object is gravity, which acts downward, thus imparting to the object a downward acceleration. Because of the object's in
