How does gravity affect an object moving horizontally?
Gravity has no effect on an object moving horizontally at a constant speed unless the object is falling downward due to gravity. In that case, gravity will accelerate the object downward while it continues to move horizontally.
What happens when there is no air resistance while Falling?
If there is no air resistance while falling, the object will accelerate at a constant rate due to gravity. This means it will continue to gain speed as it falls without any force to slow it down.
What energy transformation takes place in a falling object?
In a falling object, potential energy is converted into kinetic energy as it moves downwards. The potential energy stored in the object due to its position relative to the ground is gradually transformed into the energy of motion as the object gains speed while falling.
What directions Do the forces of air resistance and weight act on a falling object?
The weight of a falling object acts downwards, while air resistance acts in the opposite direction of the object's motion. Weight is the force of gravity pulling the object toward the ground, while air resistance is the frictional force that opposes the object's motion through the air.
What is the greatest velocity a fallen object reaches?
If air resistance is significant, after falling for a while the air resistance will be as strong as the force of gravity; the two forces will be in equilibrium, and the object won't accelerate any more. This velocity is called "terminal velocity". The amount of this terminal velocity, and the time it takes to approach the terminal velocity, depends on the specific object that is falling.
What is a freely falling projectile?
A freely falling projectile is an object that is only acted upon by gravity, moving through the air in a parabolic path while falling towards the ground. It does not have any initial horizontal force or acceleration other than gravity acting upon it.
What is the force on the ground of a 12kg acorn falling from a tree?
The impact force depends upon the height from which it has fallen (IE- its velocity upon impact), and the duration of impact (determined by the elasticity of the collision). However, the object exerts no force upon the ground *while* falling.
What is the only force affecting an object in gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.
What kind of forces act in a falling piece of paper?
The main forces acting on a falling piece of paper are gravity, which pulls the paper downward towards the ground, and air resistance, which pushes against the paper as it falls. Gravity causes the paper to accelerate towards the ground, while air resistance slows down the speed of the fall.
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
How is terminal velocity reached by a falling object?
While an object falls faster and faster, the backwards force of air resistance will increase. Once the force of air resistance equals the force of gravitation, the object will no longer accelerate, and is said to have reached "terminal velocity".While an object falls faster and faster, the backwards force of air resistance will increase.

What forces act on a falling object?
The main forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward toward the ground, while air resistance, or drag, slows down its descent by pushing upward against it. The net force of gravity minus air resistance determines the object's overall acceleration as it falls.
