Which of the following graphs shows an object at rest?

• The flat line (top)

• The line going up (second from top)

• The line going down (bottom)

• The curve (upper right)

If one doubles the mass of an object, how does the force to make it move with the same acceleration compare to the original force?

• The force is half as much as the original one

• The force is 4 times as much as the original one

• The force is twice as much as the original one

• The force is the same
