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.
Its path through space is called its trajectory. You can determine a projectileâs trajectory if you know its initial velocity. In this chapter, you will study two types of projectile motion. The top of Figure 1 shows water that is launched as a projectile horizontally. The bottom of the figure shows water launched as a projectile at an angle.
