Term
| How does the Space Shuttle take off? |
|
Definition
Hot gas shoots out from the rocket and, by conservation of momentum, the shuttle
moves in the opposite direction. |

|
|
Term
What does the Conservation of Angular Momentum of an orbital object about
the Sun mean? |
|
Definition
| When it reaches its closest distance to the Sun, its orbital velocity is highest. |
|
|
Term
| When an astronaut is weightless, he or she is freefalling. |

|
Term
| What does the Conservation of Energy mean? |
|
Definition
| Two orbital bodies interacting with one another will exchange some energy from one another. |
|
|
Term
The principle that all forces acting on an object can be summed into only one
is related to which of Newtonʼs Laws of Motion? |
|
Definition
|
|
Term
The force of gravity is an inverse square law. This means that, if you double
the distance between two large masses, the gravitational force between them |

break free of the ____ field it is located in. |
|
Definition
|
|
Term
| The strength of the force of gravity between two bodies is |
|
Definition
| inversely proportional to the square of their distance. |
|
|
Term
| The mass of Jupiter can be calculated by |
|
Definition
| measuring the orbital period and distance from Jupiter of one of Jupiter's moons. |
|
|
Term
| Changing the orbit of a spacecraft by firing thrusters is an example of |
|
Definition
| Newton's third law of motion. (Action <-> Reaction) |
|
|
Term
A skater can spin faster by pulling in her arms closer to her body or spin
slower by spreading her arms out from her body. This is due to |
|
Definition
| the conservation of angular momentum. |
