Galileo was the scientist that had ideas about falling objects tested on the moon by astronauts more than 400 years after his death.

Acceleration of a falling object?
The acceleration due to gravity for an object near the surface of the earth is approximately 9.81 m/s^2, but we can generalize this to "all falling objects" by defining falling as being attracted toward more massive object by gravitational force alone. The attractive force between the objects in this case is described by Newton's law of universal gravitation: F = G*m_1*m_2/r^2 where G = 6.67*10^-11, m_1 and m_2 are the masses (in kilograms) of the two objects, and r is the distance (in meters) between the centers of mass of the objects. The units of G are a little complicated, but this expression simplifies to units of meters/second^2, which is acceleration. Because the mass of a planet is so great compared to the mass of any object on its surface, the value of F does not change by a significant amount whether the falling object is a whale or a bowl of petunias.
What is the effect of air resistance on the acceleration of falling objects?
All objects want to stay where they are. This is a simple rule of physics. It is called Inertia. When an object passes through the molecules that are in the air, the air particles, which want to stay where they are try to force the object that is moving, or indeed as you mentioned; falling to stay in its position. Because air can not do this, you get the effect which is called terminal velocity - the speed at which an item can travel at it's maximum through our atmosphere. The effect of air means that falling objects can only hold up the constant acceleration due to gravity for a certain period of time before the object stops accelerating. Another interesting effect that objects falling at high speed heat. This is due to the object that is moving smashing into the air molecules. This transfers energy and causes heat.
How do air resistance and gravity affect a falling object?
Well, isn't that just a happy little question! Air resistance acts like a gentle breeze, slowing down the object as it falls. Gravity, on the other hand, pulls the object down towards the Earth. Together, they create a beautiful dance that determines how fast an object falls and how it moves through the air. Just remember, there are no mistakes in science, only happy little accidents!
What is the speed limit of falling objects called?
The speed limit of falling objects is called terminal velocity. This is the constant speed that a freely falling object eventually reaches when the resistance of the medium it is falling through (like air) equals the force of gravity acting on it.
How is gravity different for objects that freely fall down and those thrown upwards?
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
What is the meaning of Free Falling?
Let's imagine there is no air resistance and that gravity is the only thing affecting a falling object. Such an object would then be in free fall. Freely falling objects are affected only by gravity
How equation of motion are modified for freely falling objects?
For freely falling objects, the equation of motion is modified to account only for the effects of gravity. The equation becomes: y = 0.5gt^2, where y is the height of the object at time "t" in seconds, and "g" is the acceleration due to gravity (approximately 9.8 m/s^2). Friction and other forces are typically ignored in these scenarios.
What is the effect of the mass of freely falling body on gravitational acceleration?
No effect whatsoever. Any two freely falling bodies fall with the same acceleration when dropped in the same place on the same planet. That includes any two objects falling on Earth. Someone is sure to jump in here and point out that objects with different mass don't fall with equal accelerations on Earth, and that's because of air resistance. They may even go on to provide answers to other questions that were not asked, such as a treatise on terminal velocity. All of that is true, even if confusing. This question stipulated that the bodies in question are "freely fallling". Bodies that are falling through air are not freely falling.
What is constant for an object falling freely towards the earth?
The constant for an object falling freely towards the Earth is the acceleration due to gravity, which is approximately 9.8 m/s^2. This acceleration remains the same regardless of the mass of the object, resulting in all objects falling at the same rate in a vacuum.
Do Two objects of different masses freely fall with same momentum?
No.....because we need both mass and velocity to find the momentum if velocity is same that is 9.8m/s that is of free falling bodies.........mass will effect the final result.
Problems and solution of freely falling bodies?
Some problems with freely falling bodies include air resistance affecting the acceleration and different initial conditions of objects leading to varied outcomes. Solutions can involve ignoring air resistance for simplicity or accounting for it in calculations, as well as using proper equations to calculate the motion accurately based on the initial conditions provided.
What are the examples of freely falling bodies?
Examples of freely falling bodies include an apple falling from a tree, a skydiver jumping out of a plane, and a rock dropped from a cliff. These objects fall under the influence of gravity with only the force of gravity acting upon them.
What is the conclusion of freely falling bodies?
The conclusion of freely falling bodies is that all objects fall towards the Earth at the same rate of acceleration, regardless of their mass. This acceleration is approximately 9.81 m/s^2 and is known as the acceleration due to gravity.
Is there any force acting on an object which is falling freely?
Yes. The definition of "free fall" implies that gravity from Earth - or perhaps from different objects - is acting on the body.
What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
