F = mg
The basic formula is F = ma (F - force, m - mass, a - acclereation), but if the object is free falling we already know that his acceleration equals gravity, g.
In terms of the question that was asked, which is always a nice way to respond,
the ratio of force to mass for all freely falling objects is the acceleration of gravity.
That's always the same number, everybody wants to know why, and this question
is a super way to explain it.
The force on the falling object is its weight. F = m a
Divide each side of that equation by 'm', and you have a = F/m
Now look at that fraction. The 'F' on top is the Force of gravity, which we call 'weight'.
The more mass an object has, the heavier it is. That means that 'F' depends on 'm'.
So there's an 'm' involved in the top of the fraction, and also an 'm' on the bottom.
If 'm' changes, then the top and bottom of the fraction change together, and the
value of the whole fraction doesn't change at all. The value of the fraction stays
the same, it's the ratio of weight to mass, and that's always the same number . . .
the acceleration of gravity.

∙ 12y agoIt's the acceleration with which the body is falling. When the free fall is under the
influence of gravity, then the ratio of force to mass is the acceleration of gravity.
On Earth, that's 9.8 meters (32.2 feet) per second2 .

Is the ratio of output force to input force of a hydraulic press equal to the ratio of the output and input piston areas?
Areas
The ratio of output force to input force is the what?
It is the efficiency.
The ratio of the output force to the input force is the what of a machine?
MA ( Mechanical Advantage )
What is the ratio of output force to input force of a machine?
That's the machine's "mechanical advantage".
What is the mechanical advantage of machine that requires 30 N of input force to produce 15 N of output force?
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).

What is the describing of effect of the machine on output force?
The ratio of output force to input force for a machine is called its mechanical advantage.
What is the mechanical advantage of a machine that requires n of input force to produce 15 n of output force?
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
