Newton in Space
Exhaust gases come out and push rocket forward is a great example of this one of Newton's Laws of Motion
Newton's third Law of Motion
Fuel and oxidant mixed as a solid “cake”
Packed into a cylinder
Upon ignition fuel burns and doesn't stop
Solid Fuel
A rocket must hit this speed to stay in Low Earth Orbit (LEO)
25,000 MPH
This rocket was:
Developed to carry humans to Moon
First launched in 1967 for Apollo spacecraft–sent (8) astronaut crews to the Moon–last flight in 1973
Saturn V (five)
A rocket that has a lot of MASS, will need a lot of FORCE to ACCELERATE to the speed required to stay in orbit. This is a great example of which of Newton's laws?
F=MA or Newton's 2nd Law
Fuel and oxidizer pumped into combustion chamber
Specific liquid depends on the mission
Can be turned off and back on (unlike solids)
Liquid Fuel
This german scientist Worked with German army to develop V-2 rocket with Oberth. He surrendered to the US Army and moved to the US, working for NASA after the war
Wernher Von Braun
What was the capsule that carried the apollo astronauts to the moon called?
The command module or command service module
In space, there is no friction, no air, no wind...But which of Newton's laws is still an "outside force" that can change the motion of an object in space?
Gravity
Both solid and liquid fuel need this to burn
Oxidizer
Which of newton's laws of motion apply to a rocket as it is flying?
All of them!
What was the spacecraft called that landed the astronauts on the moon?
LM (Lem) short for landing module
Newton and Kepler both taught us that an object that is orbiting closer to another object will move __________ than an object that orbits further away
Faster
Which fuel type is:
Simple
Lower in cost
Safer to use/work with
Solid Fuel
Why did NASA put Apollo astronauts in a "parking orbit" right after launch
So that they would safely return to the earth if there were problems with their spacecraft
Nasa's next rocket, that will take us back to the moon, help us build a space station there and a base on the moon is called the SLS. What does this stand for?
Space Launch System
Newton's 1st law of motion
An object in motion (or at rest) will stay in motion (or at rest) unless acted on by an outside force
The advantage to liquid fueled rockets
They can be turned off and on.
Why are rockets staged (have multiple stages)
