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.
A trajectory is nothing more than the path an object follows as it moves through space. For this lesson, we are going to concentrate on a ballistic trajectory, which is the path an object follows through space after it is initially launched, with its path dictated only by the laws of motion, gravity and possibly air resistance.
