gravitational fields |
a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body |
|
|
terminal velocity |
the constant speed that a freely falling object eventually reached when the resistance of the medium through which it is falling prevents further acceleration |
