Abstract
The principal objectives in this project were to see if an object would move faster
with an added amount of force inside of it. In other words, Newton's Second Law of
Motion is applied to this project. The object used in my project was the bottle rocket.
There was one bottle with just air in it and another bottle that had water inside of it. The
bottle without the water moved quickly but the bottle with the water in it had much more
force and acceleration because of the added mass of the water. The equation F = ma or
force = (mass)(acceleration) is the main definition for Newton's Second Law. This law
states as follows: an object will move continually until an outside force is acted upon it;
and the greater the mass of the object the greater the acceleration it will have when the
force acts upon it. I measured the distance of both of the bottles and saw that the one
with the water went a greater distance at a faster rate. The conclusion was that the weight
of the object has an effect on its acceleration and the force acted upon it.
