Acceleration - a constant or increasing?

  1. Jul 8, 2011 #1
    1. The problem statement, all variables and given/known data
    Object A is accelerating thru a vacuum; no forces (gravity, nada) acting on the object but the force accelerating it. The force accelerating the object is removed and no friction is involved.

    2. Relevant equations
    Will the object continue to accelerate at an ever-increasing speed or will speed remain constant once force is removed?

    3. The attempt at a solution

    What does Newton's first law state?

    It's been a long time since I've been in school okay? I'm guessing law states: ... in motion stays in motion?

    F=ma. No force = no acceleration. Velocity remains constant from then on.

    Well yes but another way is that

    A body at rest stays at rest, or if moving, continues to move in a straight line with uniform velocity provided that the resultant force on the body is zero.

    So if you take away the accelerating force (or resultant force), then the ship should?

    Yea, I knew that, just wish it wasn't true sometimes. F=ma, baby.

    So, does quantum entanglement exceed the speed of light?

    Hm. Not too sure. Best to ask in the Quantum Physics section, I am not too well versed in the details of entanglement.
