3. name the three times when acceleration occurs. 4. what two things does gravitational force depend on? 5. explain the difference between mass and weight. 6. what force keeps the cup on the board?

3).  speeding up,slowing down, changing direction

4). the product of the masses of the two objects,
and the distance between their centers

5). Mass is the quantity of matter in an object.  The object's weight
is the magnitude of the gravitational force between it and another
object ... which depends on the items described in #4.

6). We can't tell, since we can't see the cup OR the board.
