Yes, the acceleration g=9.8 m/s2
The law that describes the acceleration of an apple falling from a tree is Newton's Second Law of Motion. This law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.
If you mean acceleration due to gravity it is ~9.8m/s2

That depends on the size of the apple. 5 grams is quite a small difference. The best thing to do is get an apple and weigh it.
Air resistance decreases the acceleration of a falling leaf from a tree. As the leaf falls, air resistance opposes its motion, slowing it down. This results in a lower acceleration compared to if the leaf were falling in a vacuum with no air resistance.
The statement is an example of Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In this case, the force of gravity acts on the apple, causing it to accelerate downward as it falls from the tree. The apple's mass and the gravitational force together determine its rate of acceleration.
The motion of an apple falling from a tree is an example of non-uniform motion. This is because the speed of the apple changes as it falls due to the acceleration of gravity acting on it.
If the velocity is constant then there is no acceleration. The acceleration is zero.
The apple has mass. The Earth has mass. The apple falls down, and the Earth "falls" up. The Earth's motion is not measurable. The apple's motion is.
Use the formula for constant acceleration; in the simplest case, where the initial velocity is zero, it is simply:distance = (1/2) times acceleration x time squared You can use 9.8 meters/second squared for acceleration; the distance will then be in meters.
Assuming the acceleration due to gravity is 9.8 m/s², the apple would be falling at 9.8 m/s when it hits the ground after 1 second.
acceleration remains the same
An apple falling on the ground
The acceleration of gravity is 9.8 meters per second2 downward. 1.6 seconds after falling from a branch near the surface of the Earth, the apple's speed is 15.68 meters per second. It's velocity is 15.68 meters per second downward. The tree has to be really tall, since the apple falls 12.544 meters (about 41 feet) in 1.6 seconds.
The acceleration of a freely falling body is dependended upon the mass of the two bodies involved, a mass of the apple is nothing, when compared to mass of the earth, so it tends to move downward towards earth.
Using the acceleration formula, final acceleration is the final velocity minus the initial velocity over elapsed time. Final velocity you gave as 40m/s, and the initial velocity was zero (the apple was stationary on the tree), so the difference is 40 m/s. Divided by the time you gave, 4 s, this will be 10 m/s²
-- If you really mean "falls through the air", then its acceleration steadily decreases. -- If you're actually thinking about an object that's "falling", with no air in the way and no other influence on it except gravity, then its acceleration is constant as it falls.
