In summary, the relationship between mass and free fall speed under gravity is that the heavier an object is, the faster it will fall. The size or shape of an object does not affect its free fall speed, as long as the objects have the same mass. The acceleration due to gravity affects the free fall speed by increasing it by 9.8 m/s every second. An object in free fall will continue to accelerate until it reaches the ground or another surface, and its free fall speed can be calculated using equations such as v = gt or d = 1/2gt^2.

You're probably thinking of "relativistic mass", which is now a largely obsolete concept. See:

The heavier an object is, the faster it will fall under the influence of gravity. This is because the force of gravity is directly proportional to an object's mass. Therefore, a more massive object will experience a greater force, leading to a faster free fall speed.

No, the size or shape of an object does not affect its free fall speed under gravity. As long as the objects have the same mass, they will fall at the same rate. This is known as the *principle of equivalence*, which states that the gravitational mass and inertial mass of an object are equivalent.

The acceleration due to gravity is a constant value of 9.8 meters per second squared (m/s^2) on Earth. This means that for every second an object is falling, its speed will increase by 9.8 m/s. Therefore, the greater the acceleration due to gravity, the faster an object will fall.

No, an object in free fall will continue to accelerate until it reaches the ground or another surface. This is because the force of gravity remains constant, so there is nothing to balance out or slow down the object's acceleration. However, factors such as air resistance may eventually limit the object's free fall speed.

The free fall speed of an object under gravity can be calculated using the equation v = gt, where v is the final velocity, g is the acceleration due to gravity, and t is the time the object has been falling. Another commonly used formula is d = 1/2gt^2, where d is the distance the object has fallen. Both equations assume that the object is falling from rest and there is no air resistance.
