Physicists use some basic terms when they look at motion. How fast an object moves, its speed or Velocity, can be influenced by forces. (Note: Even though the terms 'speed' and 'velocity' are often used at the same time, they actually have different meanings.) Acceleration is a twist on the idea of velocity.
Expungement is the legal process by which a court removes or erases all records of a criminal conviction, even if it is a felony conviction. Your conviction will not simply disappear on its own even if you wait 10 or 20 years - you have to take action (see how long does a felony stay on your record).
There are certain situations that preclude you from seeking expungement: 1  If the offense was a sex offense committed against a child. 2  You have a prior felony conviction. 3  You have been convicted of other violation offenses and misdemeanors in the five years leading up to the petition for expungement.
