Read each statement carefully. Write the word “CORRECT” on the space provided before each item number if the statement tells a correct idea regarding the relation between free fall and acceleration. If the statement is erroneous, write the word “INCORRECT”.
________ 1. Free fall takes into consideration the frictional force of air resistance.
________ 2. If an object is free falling onto the moon, it would not encounter any air resistance.
________ 3. Heavier objects free fall faster than lighter objects.
________ 4. Falling objects accelerate at 9.8 m/s2.
________ 5. The velocity of a ball increases at a uniform rate as it is dropped off a cliff. ________ 6. The force that causes an object to free fall is called centripetal force.
________ 7. When a baseball is thrown up into the air, the direction of its acceleration is downward.
________ 8. Terminal velocity is the starting speed an object reaches
because air resistance offsets gravity in the real world.
________ 9. When an object is dropped from a high point and falls to the
ground, its velocity increases.
_______ 10. When an object is dropped from a high point and falls to the
ground, its acceleration remains constant.
