# Simulations

```**Completion of this assignment is going to require that you describe the following force terms: normal force, friction force, net
force, gravitational force.
**A force is a push or pull between two or more objects of mass.

******FURTHER UNDERSTNDING**** THIS WILL BE ON YOUR TEST!
The gravitational attraction between two objects is dependent on____________________ and ____________
As an object falls toward Earth, air resistance due to the atmosphere gradually increases until acceleration of
the object is equal to 0 m/s. What has the objected reached?
As a satellite is launched into orbit, how does Earth’s gravity affect the satellite as it travels away from Earth?

1. What is the mission of Rosetta? Philae?
2. Why was Rosetta in interplanetary space for
so long?
3. Look up what a comet is described as. Having
read that description how would you describe
a comet in your own words?
4. What comet 67p the intended target from the
beginning of the mission?
5. Why do scientists believe comets need to be
studied?
6. What data was Philae able to send back?
7. Was/Is the mission a total failure?
8. Is Philae going to come back online?
nd
9. What role does Newton’s 2 law play?
