According to the second law of motion, force is equal to the product of mass and acceleration.

The acceleration experienced by falling objects due to the Earth’s gravitational force is called the acceleration due to gravity. It is denoted by “g” and has the same unit as acceleration, which is meters per second squared (m/s²).

The change in velocity during free fall is caused by the acceleration due to the gravitational force exerted by the Earth.

Yes, the magnitude of the velocity of falling objects changes during free fall due to the Earth’s gravitational attraction.

“Free fall” refers to the motion of objects falling towards the Earth under the influence of gravity alone, without any other external forces acting on them.
