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.

The same amount of wax exists before and after the change.

Explanation:

Chemical change is defined as a change in which arrangement of atoms present in the substance is altered and leads to formation of new substances.

Physical change is defined as a change which leads to change in shape, size or state of the substance. No new substance is formed.

1. The bonding will remain same as there is only a phase change.

2. When wax is melted, it changes to liquid state and thus density of the wax changes as now less molecules will be present per unit volume.

3. The same amount of wax will be there as there is no destruction or formation.

4. The wax can be changed back to solid state by decreasing the temperature.
