I understood exactly what you meant, Russ. I just posted for ernest's sake. I get the impression that he's being deliberately difficult.
I figured you did - I was confirming and amplifying.Jimmy said:I understood exactly what you meant, Russ. I just posted for ernest's sake. I get the impression that he's being deliberately difficult.

F=ma
a=F/m
The ratio (F_big / m_big) is equal to the ratio (F_small / m_small).
Both are the same value of "a".
What is F_big and F_small?
I understand. Thanks for the clarification. I was thinking of the force between the Earth and only one object. My fault in misunderstanding.mikelepore said:I meant, for example, drop two objects near the surface of the earth.
According to the law of gravity, all objects fall at the same rate regardless of their mass. This means that the acceleration due to gravity is the same for all objects, and therefore their speed will also be the same when dropped from the same height.
This is a common misconception, as heavier objects do not actually fall faster than lighter objects. The reason they may appear to do so is because of air resistance. Heavier objects have more mass and therefore more surface area, which increases air resistance and makes it seem like they are falling faster. However, in a vacuum where there is no air resistance, all objects would fall at the same rate.
Yes, air resistance can affect the speed of falling objects. As mentioned before, it can make heavier objects appear to fall faster due to the increased surface area. It can also slow down the speed of lighter objects, as they have less mass and therefore less resistance to air. However, in a vacuum, air resistance is not a factor and all objects would fall at the same rate.
The main factor that affects the speed of a falling object is the height from which it is dropped. The higher the object is dropped from, the longer it has to accelerate and the faster it will fall. Other factors that can have a minor effect include the shape and density of the object, as well as air pressure and temperature.
No, the mass of an object does not affect its acceleration when dropped. As stated before, all objects experience the same acceleration due to gravity regardless of their mass. This is why objects of different masses will reach the ground at the same time when dropped from the same height.
