Explanation:
6.)Can force change the mass of an object?
Force didn't make the mass of the system change. The mass of the system is simply redistributed. This would be the same as pulling apart a lump of clay and making two smaller lumps: the total mass is the same, but has been redistribute
7.)Friction drag force causes objects to slow down
8.)Where does gravity pull towards?
Where does gravity pull towards?All mass creates gravity and pulls things toward it. Here on Earth, we always feel a pull toward the center of the Earth (top), so it might seem as though there'ssomething special down there.
