2. History of Rockets
Alexandra #2
During the late 17th
century Sir Isaac Newton
organized his understandings of physical motion into
three specific laws. The laws explain why rockets work
and how they are able to work in the vacuum of space.
These impacted the design of rockets. During the end
of the 18th century and early into the 19th, rockets
experienced a revival as a weapon of war. Early in the
20th century Robert Goddard conducted practical
experiments in rocketry. While working on solid-
propellant rockets, Goddard became convinced that a
rocket could be propelled better by liquid fuel. Goddard
built the first successful liquid propelled rocket. Rockets
had a long history and it still continues today as they
are made more advanced.

Formulas
Speed- Distance/Time
Conversion of feet per second to miles per hour-
((FPS*60)*60)/5280
Conversion of average angle measure to tangent value-
Opposite/Adjacent
Conversion of miles per hour to a Mach number- 1 Mach=761
MPH, Ratio=Object Speed/Speed of Sound=Mach Number
Conversion of tangent value to height in feet for rocket
elevation- Average Angle*Tangent Value=Height

7. Newton’s Law of Motion
Newton’s First Law of Motion states that an object at rest
will stay at rest unless an outside acts upon it. Ex. Ball
Newton’s Second Law of Motion states that an object will
change velocity if it is pushed or pulled. Ex. Door
Newton’s Third Law of Motion states that for every action
there is an opposite equal reaction. Ex. Bouncing a
basketball.

8. Law that Applies to Rocket Launch
Alexandra #8
3rd
- Whenever one object exerts a force
on a second object, the second object
exerts an equal and opposite force on
the first object.
This law applies to the rocket because
when the rocket engine is set off it has
a force going downward and as an
equal and opposite reaction the rocket
goes upward.
