Direction: Read the following paragraph and choose the correct option...
The falling of a body from a height towards the earth under gravitational force is called Free fall. Such a body is called freely falling body. The acceleration of an object falling freely towards the earth does not depend on mass of object. During free fall,heavier as well as light objects accelerate at same rate.

Definition of Free Fall:
Free fall refers to the motion of a body falling towards the Earth under the influence of gravity, without any other forces acting on it. It is characterized by the absence of any resistance or support that could impede or alter the motion of the falling object.
Explanation:
When Seema dropped a coin and a piece of paper simultaneously from the same height on the terrace of a building, both objects experienced free fall. The correct answer to the given question is option 'D': The falling of a body from a height towards Earth under the gravitational force of Earth (with no other force acting on it) is called free fall.
Key Points:
To further understand why option 'D' is the correct answer, let's break down the key points:
1. Falling of a body: Free fall occurs when an object is in a state of motion where it is descending towards the Earth.
2. From a height: The object is initially at a certain height or elevation above the Earth's surface.
3. Towards Earth: The object is pulled downwards by the force of gravity, which is directed towards the center of the Earth.
4. Gravitational force of Earth: The force of gravity is responsible for the acceleration of the falling object. It acts on all objects near the Earth's surface and causes them to accelerate towards the ground.
5. No other force acting on it: In free fall, there are no external forces acting on the object that could oppose or alter its motion. This means there is no air resistance, no support, and no other force counteracting the force of gravity.
6. Prohibited from falling down: Option 'C' is incorrect because free fall does not involve any prohibition or restriction on the motion of the falling body. Instead, it describes the natural motion of an object under the influence of gravity.
7. Many forces acting on it from all sides: Option 'A' is incorrect because free fall specifically refers to the motion of a body with no other forces acting on it, apart from the gravitational force. The presence of multiple forces would not constitute free fall.
8. Fall of the body from one medium to another: Option 'B' is incorrect because free fall is not limited to a transition between different mediums. It can occur in a single medium, such as air or vacuum, as long as no other forces are acting on the object.
Therefore, the correct answer is option 'D', which accurately describes free fall as the falling of a body from a height towards Earth under the gravitational force of Earth, with no other forces acting on it.
