Aristotle didn't use the word "acceleration," but he did state (incorrectly) that heavier bodies fell faster to the surface of the Earth than did lighter bodies.
The poet-philosopher Lucretius MAY have reached a different conclusion, but certainly did no experiments.
Writings prior to Galileo Galilei state that Aristotle had been shown to be wrong, but give no details.
Dutch scientist Simon Stevin did actual experiments in 1586 with dropped balls and proved conclusively that Aristotle was wrong. However, he also did not use the word "acceleration."
Galileo did a mathematical description of balls rolling down a plane, and showed that such bodies experienced constant acceleration. He then speculated that objects falling straight down would do the same. There is no credible evidence that he did any experiments on such objects, as he did not have the instruments to accurately measure their rate of falling.

Is there acceleration in the y direction?
Yes , there is a constant acceleration is the y- axis. and that acceleration is called acceleration due to gravity or Gravity. Gravity attracts every falling body which is on y axis. that's why the gravity is on y axis which is constant
What is the constant for gravity?
The constant acceleration due to gravity on EARTH is -9.81 m/s^2. This constant does not apply to objects on other planets because the mass of another planet might not be the same as Earth's mass. Because acceleration due to gravity is constant, this will be the acceleration due to gravity no matter the position of the object on Earth.
What is the relation between the potential energy and acceleration due to the gravity?
The two are unrelated. Potential energy depends on height; acceleration due to gravity is more or less constant.
How is acceleration due to gravity be zero in a parachute?
At terminal velocity (constant velocity), the acceleration is zero, but prior to that, there is a downward acceleration.
How do you find acceleration due to gravity when gravitational constant is given. tell the formula?
Acceleration due to gravity in the vicinity of a mass 'M' is A = G M / R2 A = the acceleration G = gravitational constant M = mass of the mass R = distance from the center of the mass 'M'

Why gravitational constant is constant while when acceleration due to gravity is change?
gravity of earth is constant in any plane but the acceleration may vary becoz of irregular plane
Can acceleration due to gravity vary with respect to height?
No, acceleration due to gravity is a constant at 9.81ms-2. It cannot be influenced by other factors such as height.

How acceleration due to gravity value is calculated?
The acceleration of gravity due to a single object is(Universal gravitational constant) x (Mass of the object)/(distance from the object's center of mass)2
Why is weight directly proportinal to mass?
Weight = mass x acceleration due to gravity As acceleration due to gravity remains constant at a given place, weight becomes proportional to the mass
What happens to the acceleration due to gravity of an object in projectile?
nothing happens to it, it stays constant.
Is a constant acceleration graph a linear equation?
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
What is the acceleration due to gravity if an object falls down from a height of 25 m?
The acceleration due to gravity remains constant throughout the fall i.e. 9.8m/s2 ( taken as 10 for calculations).
