Free Fall Motion.
As learned in an earlier unit, free fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

**Answer:**
The correct answer is option 'D', to create a situation where the air resistance is negligible.
The law of free fall under gravity states that all objects, regardless of their mass, fall towards the Earth with the same acceleration when the effect of air resistance is neglected. This acceleration is known as the acceleration due to gravity and is denoted by 'g'. It is approximately equal to 9.8 m/s^2 near the surface of the Earth.
**Air Resistance and Free Fall:**
Air resistance is the force exerted by the air on a moving object. When an object falls through the air, the air resistance opposes its motion. The amount of air resistance depends on the shape, size, and speed of the object. For objects falling at relatively low speeds, such as a feather or a piece of paper, the effect of air resistance is significant and cannot be ignored. In such cases, the object reaches a terminal velocity, where the air resistance is equal to the weight of the object, and the object falls with a constant speed.
**Negligible Air Resistance:**
To study the law of free fall under gravity, it is important to eliminate or minimize the effect of air resistance. This can be achieved by creating a situation where the air resistance is negligible. In such a scenario, the object falls freely under the influence of gravity alone, and its motion can be accurately described by the law of free fall.
**Advantages of Negligible Air Resistance:**
1. Simplifies Analysis: Negligible air resistance simplifies the analysis of the motion of falling objects. It allows us to apply the laws of motion and perform calculations without considering the complex effects of air resistance.
2. Consistent Results: When air resistance is negligible, all objects, regardless of their mass, fall with the same acceleration. This allows for consistent and predictable results, making it easier to study the fundamental principles of free fall.
3. Experimental Accuracy: By eliminating or minimizing the effect of air resistance, experimental measurements can be more accurate. This allows for the precise determination of the acceleration due to gravity and the verification of the law of free fall.
In conclusion, to accurately study and apply the law of free fall under gravity, it is better to create a situation where the air resistance is negligible. This simplifies the analysis, provides consistent results, and allows for more accurate experimental measurements.
