\nIn physics, a “freely falling object” is ideally defined as an object that is accelerating due to gravity only, with no other forces acting on it (specifically, negligible air resistance).
\n– A) It accelerates: Correct. It accelerates downwards due to gravity (acceleration due to gravity, g).
\n– B) Its momentum keeps on changing: Correct. As it accelerates, its velocity changes, and momentum (mass x velocity) therefore changes.
\n– C) Its motion is affected only by the gravity: Correct. This is the definition of free fall in an ideal scenario (e.g., vacuum).
\n– D) Its motion is affected both by the gravity as well as by the air resistance: This statement is not correct for a *freely falling object* as defined in physics. Free fall explicitly excludes significant air resistance. While real objects falling in an atmosphere experience both, the term “freely falling object” usually implies the ideal case where air resistance is negligible.
\n<\/section>\n
\n– Free fall is motion under the sole influence of gravity.
\n– Air resistance is typically ignored in the definition of free fall.
\n– A freely falling object accelerates and its momentum changes.
\n<\/section>\n
\nIn practical scenarios, objects falling through air do experience air resistance, which opposes the motion and increases with speed. Eventually, a terminal velocity is reached when air resistance equals gravity. However, the term “freely falling” in the context of fundamental physics principles often refers to the ideal case without air resistance.
