Final answer:
When two different bodies are dropped from the same height and at the same time, they will both accelerate downward at the same rate. The influence of the acceleration of gravity cannot be controlled or diminished. Factors that can influence the speed of an object during free fall include air resistance, surface area, and weight distribution.
Step-by-step explanation:
When two different bodies are dropped from the same height and at the same time, they will both accelerate downward at the same rate. This is because in the absence of air resistance and friction, all objects fall toward the center of Earth with the same constant acceleration, regardless of their mass.
The influence of the acceleration of gravity cannot be controlled or diminished, as it is a fundamental force that acts on all objects. The only way to change the acceleration due to gravity is by changing the location, such as going to a different planet or altitude.
The speed of an object during free fall is influenced by factors such as air resistance, surface area, and weight distribution. Objects with more surface area experience more air resistance, which can slow down their fall. However, in the absence of air resistance, all objects would fall at the same rate, regardless of their size or shape.
