9.8 meters per second squared on or near the Earth
acceleration due to gravity is not affected by the presence or absence of air
No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
Unless you drop the feather in a vacuum, air resistance will be significant, so any acceleration (change in velocity) will not be due solely to gravity.
I think you should master basic English before trying Physics.
The weight of an object is defined as the force acting on it due to gravity. This force is equal to the mass of the object multiplied by the acceleration due to gravity (9.81 m/s^2 on Earth). So, weight = mass x acceleration due to gravity.
True. In free fall, all objects experience the same acceleration due to gravity regardless of their mass or air resistance. The acceleration due to gravity is approximately 9.8 m/s^2.
acceleration due to gravity of earth is 9.8ms-2
Acceleration due to gravity on Saturn = 11.171 m/s2 (9.807 m/s2 on Earth)
I suppose you are asking about what forces change when acceleration due to gravity changes. In this case, the formula for forces concerning acceleration due to gravity is as such: fg=mg. When acceleration due to gravity(g) changes, it affects the force of gravity which is also known as the weight of the object. This is shown as fg.
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
No, acceleration due to gravity does not change the weight of an object. Weight is determined by the mass of the object and the acceleration due to gravity in that location. The acceleration due to gravity affects the force with which an object is pulled toward the center of the Earth, leading to its weight.
Acceleration due to gravityThe acceleration produced in the motion of a body under gravity is called Acceleration.
The period of a pendulum (in seconds) is 2(pi)√(L/g), where L is the length and g is the acceleration due to gravity. As acceleration due to gravity increases, the period decreases, so the smaller the acceleration due to gravity, the longer the period of the pendulum.
