Galileo Galilei
Aristotle proposed that the speed at which an object falls is not proportional to its mass. He theorized that all objects fall at the same rate regardless of their mass. This was later experimentally confirmed by Galileo.

Depends what u mean by that. If it is free falling it would obviously be accelerating at 9.8m/s^2. If there is an incline then it depends. I believe acceleration is directly proportional to velocity though.
For example, you can time how long it takes for an object to reach the floor. You also need to measure how far it falls down. If you assume constant acceleration, there is only one possible acceleration for any possible set of measurements.
The answer is 91 ft, of course!
A proportional model of a three dimensional object is an scale model.
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.
An object's density is inversely proportional to the object's volume. As the volume increases the density decreases, and vice versa.

The kinetic energy of a falling object is directly proportional to the distance it falls.But the distance is not directly proportional to the time in fall, so the KE is not directly proportionalto the time either.
Gravity causes falling objects to accelerate.
No, acceleration is not directly proportional to weight. Weight is the force of gravity acting on an object, while acceleration depends on the net force acting on the object, which can be influenced by factors other than weight, such as friction or applied forces.
