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).
If you were convicted of one of the following crimes, you can petition for expungement if more than five years have passed since you satisfied the conditions of your diversion agreement, probation, sentence, parole, or post-release supervision: 1  class A, B, or C felony. 2  off-grid felony, after July 1, 1993.
