What will happen during the free fall of a massive object under the influence of gravitational force of the earth ?
Velocity of the massive object increases
The correct answer is Option 4 i.e. Velocity of the massive object increases .
During the free fall of a massive object under the influence of Earth’s gravitational force, the velocity of the object increases. This happens because the only force acting on the object is gravity, which causes it to accelerate towards the Earth. The acceleration due to gravity is approximately 9.8 m/s², meaning the object gains speed by 9.8 meters per second every second it is falling (ignoring air resistance). This increase in velocity continues until the object hits the ground or another force opposes its motion. Importantly, during free fall, no energy is added to or removed from the object by any other means—gravity alone does the work. The object's mass remains constant, and only its velocity and kinetic energy change due to gravitational acceleration.
Other options explained:
-
Mass of the object increases: An object’s mass remains unchanged during free fall.
-
Mass of the object decreases: Mass is constant and unaffected by motion.
-
Velocity of the object decreases: – In free fall, velocity increases due to gravitational pull
