Newton's+First+Law

=If an object is not moving, it will not start moving by itself. If an object is moving, it will not stop or change direction unless something pushes it.= [|http://www.grc.nasa.gov/WWW/K-12/UEET/StudentSite/dynamicsofflight.html#lawofmotion]

I have no idea why the coin fell into the cup (maybe it is heaviness). The stronger I force the card to move the faster it goes. When the card hits the table it becomes slower and comes to rest again, and the coin that fell into the cup also comes to rest. Now everything is still."
