Orbiting Satellites

Objective: Explain how a rocket lifts off the ground and what keeps an object in orbit

-> How Do Rockets Lift Off?
    1.  Which of Newton's laws explains the lifting of a rocket into space?
 

    2.  When a rocket rises, what causes the action force?
 
 

    3.  When a rocket rise, what causes the reaction force?
 
 

    4.  On the diagram of a rocket lifting off the ground, draw and label arrows that show the action force and the reaction force.

    5.  When a rocket lefts off the ground, the net force is in an upward direction.  Is the upward pushing force greater or lesser than the downward pull of gravity?
 
 
 
 
 

->What Is a Satellite?

    6.  Any object that travels around another object in space is a(n) _________________

    7.  An object traveling in a circle is accelerating because it is constantly changing_______________

    8.  What is a force called that causes an object to move in a circle?

    9.  For a satellite, what is the  centripetal force that causes it to move in a circle?

    10.  Is the following sentence true or false?  Satellites in orbit around Earth continually fall
toward Earth. _________________________

    11.  Explain why a satellite in orbit around Earth does not fall into Earth.
 
 
 
 
 

    12.  A satellite is a projectile that falls ____________________Earth rather than into Earth.

    13.  Why doesn't a satellite need fuel to keep orbiting?
 
 
 
 
 

    14.  What force continually changes a satellite's direction?
