Record the height of the person using the meter sticks that are attached to one of the wooden beams. Analysis In order to determine the center of mass of a person, we used the formula for torque: Στ = rF The torques due to the weight on each end of the person were set equal to...

Assuming covariance of dynamical laws under quantum coordinate transformations, this allows to use known physics to determine the dynamics. We apply this procedure to find the motion of a probe particle and the behavior of clocks near the mass configuration, and thus find the time dilation caused ...
