Principles: The Law of Momentum

Principles: The Law of Momentum

On May 30, 2020, Space X and NASA launched a rocket into space. It was the first time NASA worked with a private company—an important milestone in the history of space travel.

It takes an unimaginable amount of energy to launch a rocket into space. Space X's Falcon 9 rocket weighs 1.2 million pounds (549 thousand kilograms).

One way to look at the launch of a 1.2 million pound rocket is through Newton’s laws of motion. Newton’s first law states that every object will remain at rest unless it’s forced to change its state by the action of an external effort.

If there’s no external force on an object, there will be no movement whatsoever. But if you apply external force to that object, the movement of the object will change because of that force.

The key to everything in life that requires motion is this question:

How much force do you need to get an object moving?
