The property of force

  1. Apr 23, 2009 #1
    I have a problem, in Newton's second law F=m*a in inertial frame. In the accelerated frame a mass should be affected by a inertial force, but the force in the original inertial frame don't change, so real force is just like the temperature and will be the same in different frames?

    Yes, the real forces are the same in any frame. But inertial pseudo-forces only appear when viewing motion from a non-inertial frame.

    If I were in a NASA centrifuge and viewing a ping pong game in the Earth's inertial frame (neglecting coreolis forces), would the game look the same if I were in an inertial frame, and the game were being played in the centrifuge?
