Answer:
[B] uniform acceleration
Explanation:
The motion of an object under free fall is best explained by understanding the fundamental concepts of motion and forces.
An object under free fall is influenced solely by gravity, neglecting air resistance. An object in free fall exemplifies motion under the influence of gravity, which characteristically results in uniform acceleration. Since gravity provides a consistent force, the object accelerates at a uniform rate. Therefore, the velocity of the object increases linearly over time as it continues to fall.
Given that the acceleration remains constant throughout the fall, the motion of an object under free fall is an example of uniform acceleration making the correct answer [B].
