Rockets use the principle of Newton's third law of motion to provide thrust by expelling gases from the engine. There are two main types of rocket fuel: solid fuel and liquid fuel. Rockets are used to launch satellites into orbit around Earth. Satellites orbit Earth to provide applications such as communications, weather monitoring, navigation, and more. Key differences between rockets and satellites are that rockets are powered by onboard fuel while satellites use inertia and solar power to remain in orbit.

Endeavour Space Shuttle
The visit to Endeavour Space Shuttle in Los Angeles provided me with a deeper insight of how physics principles are applied in real life. Not only did I learn of how the rockets get propelled into space, but also gained a better understanding of how the satellites are injected into orbit after the rocket gets into space. As I strolled into the facility, I was excited since I finally had the chance to get the answers to the several questions that crammed in my mind regarding rockets and satellites. Before the visit, questions such as how does the spacecraft travel with accuracy and know where it’s going? Once it reaches the orbit, what keeps it in motion? Besides, can any place be chosen for the launch of the rockets? Even more importantly, I was fascinated to learn the various structural parts of the rockets and the fuel used in its operation.
The process of rocket propulsion was illustrated to me just like I had learned in my theoretical physics. Essentially, a rocket is propelled forward due to a rearward ejection of burned fuel that was initially in the rocket. Consequently, the forward thrust gained by the rocket is as a result of the back force of the ejected burning fuel. In the end, the rocket propulsion principle confirmed Newton’s third law of motion which states that action and reaction are opposite yet equal forces. Unlike the jet engine that depends on drawing in air to burn the fuel, the rockets utilize the fuel on board which is a mixture of liquid oxygen and hydrogen to cause combustion ensuring that they can operate in space where a vacuum exists. I was also intrigued to learn that the rocket didn’t work on the principle of pushing against the ground, or air but depended solely on the thrust force provided by the burning fuel. I also realized that for a large weight of rockets is dominated by fuel. As such, for massive uplift force to be achieved by the rocket, the fuel has to be burned at a rapid rate. This would ultimately ensure that the rate of change of momentum is huge and therefore causing the propulsion force to be sufficient to cause uplift. Certainly, this principle was in line with Newton’s second law of motion which suggests that the magnitude of force on a moving body is directly proportion to the rate of change of its momentum {F = (v-u)dm/t}.
The second fact that I learned at the science facility is that the earth is shielded from radioactive particles from the sun by an electromagnetic field around it. As such, when the rockets pass through the layer of the earth’s electromagnetic field, it may get charged and risk burning when leaving or entering the earth’s atmosphere from space. Therefore, the rocket’s nose is designed to be curved instead of being sharp pointed in order avoid the concentration of charges that may in the end build an electrical potential difference capable of destroying the rocket. Certainly, this principle reiterated the electrostatic cha.

4- Enabling human beings to survive in space and in habitable places outside Earth
How fast can an atmosphere travel round it's planet? "Normal" rotation on Ear...wonderdome
Wouldn’t it be wonderful to live on a planet with a non-rotating atmosphere to be able to travel places by just jumping into the air and hovering long enough? Sounds fantastic, right? The problem is, when a planet turns and the air does not, things get really windy. As in “a thousand miles per hour wind speed “ windy.
Luckily for us, we don’t experience it here on Earth. The Earth’s atmosphere travels in sync with our planet and completes one turn around its axis in roughly 24 hours. Phew!

The Unprecedented Rosetta mission to Comet 67P/Churyumov–GerasimenkoThomas Madigan
After almost 11 years in transit and 4 gravitational assists from the Earth and Mars, the European Space Agency’s Rosetta probe has arrived at the Jupiter-family comet 67P/Churyumov–Gerasimenko. Arriving on Wednesday, August 6th, the probe went into a 100 km-high orbit around the comet, both of which are now in common orbit around the sun. Depending on the comet’s activity, Rosetta will come as close as 10 km to the comet’s nucleus over the course of the mission. With a high orbital eccentricity (the orbit’s deviation from a perfect circle) of 0.640, a perihelion of 1.2 AU and an aphelion of 5.68 AU, 67P/Churyumov–Gerasimenko is now in common orbit around the sun with Rosetta.
Rosetta is a cornerstone mission of the European Space Agency (ESA). It is an unprecedented landmark achievement in human history and the history of science. Humankind has placed a sophisticated instrument of science in orbit around a comet's nucleus and has placed a robotic lander in the surface of that nucleus! Rosetta will chase down, go into orbit around, and land on the object of interest. It will study 67P/Churyumov-Gerasimenko with a combination of remote sensing and in situ measurements. The mission has 2 phases, the ongoing orbital phase and the landing phase. During the ongoing orbital phase, the spacecraft will examine the comet up close with its suite of 11 instruments. During the landing phase, the orbiter will release the Philae lander which carries an onboard suite of 10 instruments for imaging and sampling the comet’s nucleus. The mission will track the comet through perihelion, its closest approach to the sun, examining its behavior before, during and after.
Providing an introductory retrospective of comets, sometimes regarded as harbingers of doom, Prof. Madigan discusses this historic mission, a mission that includes study of the comet from the surface of its nucleus!
This public event was hosted at the Ross School (East Hampton, NY) by the Montauk Observatory on September 18th, 2014.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

4. History of Rocket
The Chinese is claimed by many to be the inventor
of the black powder (about 200 B.C – 2216 Years
back) and thus the rockets
India should be honored instead of China for the
Rocket Crackers during Diwali & Temple Festivals
5000 Year old Tradition
5.
6. Contd.
The Chinese also developed rockets and flame
torches to be used in combat against their main
enemy, the Mongols.
10. A balloon is a simple example
of a rocket.
Rubber walls compress
the air inside. Air
escapes from the small
opening at one end and
the balloon flies.
11. Action and Reaction
A rocket takes off only when it
expels gas.
Action: The rocket pushes the
gas out of the engine.
Reaction: The gas pushes up
on the rocket.
UP
DOWN
12. DRAG-Opposing Force
DRAG = Air Resistance
Air Resistance causes friction which
slows down the Rocket. Friction
always works in the opposite direction
of the Rocket’s motion.
(Even when a rocket is descending,
drag counteracts the rocket’s motion!)

13. TIPS: REDUCING DRAG
More
AERODYNAMIC or
pointed nose cone: This
causes the air to “part”
around the bottle.
More Aerodynamic
fins:
Thinner, more streamlined
fins reduce drag. Position
fins toward the tail of the
rocket (moves CP!).
A Round or Contoured
Nose Cone allows Air to
easily separate, thus reducing
the effects of Drag
Drag has a significant
effect on blunted bodies,
such as the Nose Cone
below.
14. Rocket Fin Shapes
Square/Trapezoidal Fins yield MORE stability, but create MORE drag.
Triangular/ Epsilon Fins introduce LESS drag, but yield LESS stability.
15. Thrust
Forward motion or
thrust can best be
described by observing a
balloon filled with air.
When air is released
from the balloon, forces
inside the balloon cause
it to move to the left.
16. The Action (Thrust) has to be greater than
the weight due to gravity of the rocket for
the reaction (liftoff) to happen.
17. Weight
Weight is the force generated by the
gravitational attraction on the rocket.
More the Weight more the Thrust required to
push
18. Lift
The lift force (the aerodynamic force
perpendicular to the flight direction) is used
to overcome the weight.
On a rocket, thrust is used in opposition to
weight.
On many rockets, lift is used to stabilize and
control the direction of flight.
19. Stability During Flight
The purpose of
putting fins on a
rocket is to provide
stability during
flight, that is, to
allow the rocket to
maintain its
orientation and
intended flight
path.
20. Stability During Flight…
Think about a dart…
Fins or feathers in the
rear act like wind veins
and trail behind.
Heavy mass made of
metal carriers the
momentum.
21. Type of Fuel Used
Solid Fuel Rocket
Liquid Fuel Rocket
Water Pressure Rocket
22. Solid Fuel Rockets
Fuel in solid form burns and is
converted to hot gasses.
Hot gasses expand and create high
pressure.
Pressure escapes out nozzle, pushing
against air and rocket body equally.
23. More on Solid Fuel Rockets
Solid-fueled rockets
use a fuel and
oxidizer in solid
form.
The fuel and
oxidizer are in a
powdery or rubbery
mixture known as
the grain or charge.
24. Once a solid-fueled
rocket is ignited, it
burns completely.
There is no way to
stop the combustion
or to change the
amount of thrust.
More on Solid Fuel Rockets
25. Liquid Fuel Rockets
Work on same basic principles as solid
fuel.
Carry liquid fuel and oxygen.
Unlike solid fuel, liquid fuel can be
regulated to control thrust.
26. … Liquid Fuel
Used for launches and interplanetary travel,
liquid fuel rockets
More versatile than solid rockets because the
amount of thrust can be controlled, but they are
less reliable than solid rocket engines.
27. Water Rockets
Instead of hot gasses creating pressure, we
use a bike pump and store pressure.
Action: Expelling water from engine bottle
(water is forced down)
Reaction: Water resisting against rocket
body (Rocket is forced up)
31. Propulsion
All spacecraft need to reach about 17,500 miles per
hour to get into orbit.
Thrust is used to push the spacecraft this fast.
Thrust is produced by burning a rocket fuel with
oxygen.
If there is not enough thrust the spacecraft will fall
back to earth due to gravity.
32. Fixing a Satellite in an Orbit
How fast is this? R ~ 6400 km = 6.4106 m,
so you’d need a speed of
sqrt[(6.4106m)(10m/s2)] = sqrt (6.4107)
m/s, so:
v 8000 m/s = 8 km/s = 28,800 km/hr ~
18,000 mph
42. Difference between rockets and
satellite
Rockets Satellite
Rockets are powered by their
own motors with fuel tanks,
usually going up unless there
is a malfunction.
Satellites, on the other hand,
are powered by gravity's
inertia and usually solar
power with small guidance
boosters to keep them in
orbit for longer periods.
Rockets carry the satellites Satellites orbit while rockets
go up.
Satellites orbit a planetary
body, such as the Earth or
moon, or any other object in
space.
43. How many satellites are
in orbit?
There are approximately 9,000.
At the time of this writing, there were
8,953 satellites in orbit around Earth
including 4,503 larger pieces of space
junk.
44. What’s the path of the satellite?
Geosynchronous orbit -- Circle
45. What do you mean by natural and artificial
satellite?
Artificial satellites are man made while natural
satellite are formed by nature.
Artificial satellites need energy for installation and to
rotate around any planet while natural satellites do
not require any energy for revolving.
Artificial satellites move closer than the natural
satellite. Some examples are weather satellites
(GOES), communication satellites (ANIK),
navigation satellites (GPS), scientific satellites
(TERRIERS), and military satellites (MILSTAR).
46. Moon is a natural satellite and the earth can also be
considered a satellite of the sun are examples of
natural satellite.
What do you mean by natural and artificial
satellite?
47. How long it will take for a satellite to get into its
orbit?
Depends on where in space and the speed of the
aircraft … The shortest trip to the Moon took place in
January 2006 by the NASA Pluto probe New
Horizons. With the speed of 58,000 km/hr, it only
took 8 hours and 35 minutes to get to the Moon from
Earth. Apollo missions took about three days to
reach the moon. It will take minimum 6 hrs to reach
international space station
48. What is the life span of satellite?
Around Ten years
49. What will happen to the debris of rocket?
Most everything that does fall back to the earth
burns up in the atmosphere upon reentry. This is
because of the friction generated by the atmosphere
on the debris.
50. How many launch pads are in India?
Four
Vikram Sarabhai Space
Centre,thiruvananthapuram,thumba
Balasore,odisha
Satish Dhawan Space Centre, Sriharikota, Andhra
Pradesh
Abdul Kalam Island, Odisha
51. Does the time of flight vary with the altitude?
Yes
52. What’s the distance between the earth and the
orbit?
Geostationary orbit, geostationary earth
orbit or geosynchronous equatorial orbit
(GEO) is a circular orbit 35,786 kilometres
(22,236 mi) above the earth's equator . satelite's
in high geostationary orbits 23,000 miles about
37,000km are beyond the van allen radiation belt
Low earth orbit which is a satelite orbiting below
2000 km between the radiation belt and the earths
atmosphere.
53. Why launch pads are located near seashore?
The launching stations are generally located near
eastern coast line so that, just in case of failure of the
launch, the satellite does not fall on built-up
hinterland.
