Question 4 • Physics I

Which object would be considered to be in free fall?

Answer
A
one that is truly weightless
B
one that is slowed down by air resistance
C
one that experiences both friction and centripetal force
D
one with only gravity acting upon it

Explanation

An object is in free fall when gravity is the only force acting on it. Therefore, the object with only gravity acting upon it is in free fall. Air resistance or friction means another force is also acting, and being weightless is not the definition of free fall.
