Re: [Phys-l] FW: The "why" questions



I think so, however, my first sentence below is c***. The COM does move in the direction of the applied force. (Are there unapplied forces?)

bc hangs his head in shame

When a real body attains the acceleration a=F/m it will be in a deformed
condition.
The regions closer to the point of application of force will be having
greater compression
than the regions at the free end. This deformation also takes finite time.
The situation can be visualized by point masses connected by springs.
But this deformed state so attained will be changing in time as the
longitudinal wave is reflected back and forth unless a standing wave is
formed.

Hope I have got it right.

Sarma.

Nope, at least not here. The C of M moves toward the point of the applied
force until the shock wave reaches the new position of the C of M.
