Understanding Newton's Third Law Through Real-World Events
Written on
Chapter 1: The Power of Push and Pull
The concept of push and pull is not just theoretical; it has profound implications in our everyday lives. One of the most fundamental principles in physics, often quoted as “For every action, there is an equal and opposite reaction,” deserves closer examination.
Isaac Newton's third law of motion suggests that every action force triggers a corresponding reaction force in the opposite direction. This idea likely originated from Newton’s observations of various physical interactions. A classic illustration is when you leap into the air: your legs exert force downwards against the ground, which, in turn, pushes back with equal force, propelling you upward.
This fascinating dynamic demonstrates the unseen mechanics behind daily activities we often take for granted.
Section 1.1: A Real-Life Application
To better understand the practical application of Newton's third law, let’s delve into a remarkable incident that showcases the immense power unleashed when opposing forces interact.
Subsection 1.1.1: The Tugboat Incident
In 2010, a modest tugboat was tasked with guiding a colossal oil tanker out of port near Alexandria, Egypt. The tanker measured 850 feet and weighed around 200 times more than the small tugboat! At first glance, one might assume the tug would struggle against the tanker’s weight. However, the tugboat was able to maneuver effectively because of Newton's third law: as the tug exerted force on the tanker, the tanker responded with an equal and opposite force, enabling successful navigation.
But then, disaster struck.
The towline connecting the tugboat to the tanker unexpectedly broke, leading to a chaotic chain of events. With the opposing forces eliminated, the massive tanker continued forward while the tugboat was thrust backward.
As a result, the tanker, driven by its considerable momentum, crashed into a nearby port terminal. The terminal then exerted an equal force back on the tanker, causing significant damage to both vessels.
Section 1.2: The Aftermath of the Collision
The incident did not end with the collision. Floodlights from the accident ignited leaking oil, resulting in a devastating explosion that blasted the tanker out of the water. The fiery chaos spread like wildfire, igniting nearby pipelines and terminals, creating a disaster reminiscent of military airstrikes.
Within hours, the terminal lay in ruins, pipelines burned, and the tanker sank, while the local community faced a significant disruption.

The repercussions of this disaster extended far beyond physical destruction. Tragically, eight crew members lost their lives, over
