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).
Felony convictions are not automatically expunged with the passage of time but require the filing and granting of an Expungement Petition by the Court. Many felony cases are wobblers; that is, they can be reduced to misdemeanors (even after many years) and then expunged in the same court proceeding.t is a common misconception that felony cases cannot be expunged; this is incorrect-if a felony conviction resulted in successful probation (not an actual prison sentence) the case can probably be expunged. Certain sex offenses are specifically exempted from expungement.
