THRUST EQUATION

Momentum thrust is based on Newton's Second Law, which can be stated in words as force equals mass times acceleration or mathematically as:

F = ma

A cannon is a good example to demonstrate this relationship. When a cannon is fired, a controlled explosion of fuel and oxidizer occurs inside the barrel.

The resultant gases from this explosion propel the cannon ball out the open end of the barrel.

Both the cannon and cannon ball experience acceleration and movement.
