A hammer and a pencil are dropped simultaneously from the same height. Neglecting air resistance, which of the following is true?

• the hammer accelerates faster because it is heavier.

• the hammer accelerates slower because it has more inertia.

• the pencil accelerates faster because it has a smaller mass.

• the both accelerate at the same rate.

Newton's third law refers to "action-reaction forces". These forces always occur in pairs and....

• act in the same direction

• always act on the same object

• always act at right angles

• never act on the same object
