24. Which of the following statement(s) about the freely falling objects is/are FALSE? Freely falling objects are the objects falling from a height towards the earth under gravitational force of the earth. The acceleration of a body falling freely towards the earth depends on the mass of the body. If an object is dropped freely from a height, its initial velocity 'u' is zero and if an object is thrown vertically upwards, its final velocity 'v' becomes zero.
