review quiz on Newton's laws of motion and gravity

1. An object that is moving with constant velocity
   will tend to _________________________________
   unless a ______________ acts on it.
   
2. An object sliding on ice will slide [more/less] distance than an object sliding on a carpet. This means that the tendency of an object to stop moving is
   [a property of the object/
   a property of the friction force caused by the object it is sliding on].
3. If the Earth pulls on the baseball, the baseball [will/will not] pull equally on the Earth.
4. If the Earth pulls on the baseball, the baseball [will/will not] move the same distance as the Earth.
5. Newton's third law says that if object A exerts a force on object B, then _____________________________________
6. Newton's second law says (in words) ____________________.
7. Newton's second law says (as an equation):_______________.
