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 The path that a moving object follows is called its trajectory. # An object thrown horizontally is accelerated downward under the influence of gravity. # Gravitational acceleration is only vertical, not horizontal . # The object Ãs horizontal velocity is unchanged, if we can neglect air resistance . Projectile motion involves the trajectories and velocities of objects that have been launched, shot, or thrown.
