World Trade Center’s Twin Towers, Newton’s Third Law &
In July 2001, just two months before the terrorist attacks of September 11, the Port Authority
agreed to lease the twin towers to Larry Silverstein, a New York City
developer. Silverstein agreed to pay the equivalent of $3.2 billion over the next 99 years.

‘FOR EVERY ACTION, THERE IS AN EQUAL AND OPPOITE RE-ACTION’
Everyone agrees the towers were largely pulverized into dust and small debris. When
pulverization is the outcome of the event then it changes the physics drastically
compared to other building collapses.
NEWTONS 3RD LAW OF MOTION
For every action there is an equal and opposite reaction. Scientists like to use this
law for gravity and rockets but it applies to all motion and the forces they exhibet.
When we apply this to the WTC in layman’s terms it means a small mass cannot
completely crush a large mass.
There is not enough potential energy in the smaller mass to generate the force. It
would require the lighter item to have additional energy to pulverize the larger
section of the building. The force applied is the same on both sections. In the
collapse both items are the same structure and composition. Let’s look at an
example of this:
Here are both sections of the building at the time of collapse. If 10 floors on the
top are pulverized then 10 floors on the bottom must also be pulverized. The
same amount of force used to pulverize the bottom must also be applied to the top
