How much energy in a falling mass, for energy storage

Ancient cultures have always looked to using weight as a method of storing energy, from the first cranes who used counter weights as balancing masses to build structures
To uses of water wheels
Here I will be covering how to figure out how much energy you have

And how much energy you can of this amount, just like you can't squeeze every drop of orange juice out of a orange you can't get every bit of energy out of anything
Start by knowing the mass of the object
Let's say you have 200 kilograms in weights
And your roof is 10 meters up (thats about 30 feet)
To calculate this your. Just need to know how hard is the object in pushing down (the force of it's weight)
And how far it can push that hard
Force =mass x acceleration
and energy= force over a distance
So we know the mass 200kg
The acceleration is the rate at which things speed up as they fall
On earth this is 9.8meters per second per second
So every second the falling object is going 9.8 meters per second faster
So if the force
So 200 x 9.8 = 1960
For the force is constantly 1960
But for how far
Well your roof is 30 meters high
So 1960 x 30 =58,800
is just the number of " joules" or
watts seconds
But what to can you power with this and for how long
Well to determine this look at the wattage of your appliance or item
Lets say a good LED bulb so 10 watts
If you divide the watt seconds by the wattage you will get the time you can use them for
So 58800/10= 5880 seconds

Hmm seconds arent useful many minutes 5800/60 =
98
So 98 minutes
1 hour and a half of lighting for a room it's reasonable but also sucks
What if I had 300kilos ? How long will the light stay on?...

What if I use a ham radio instead and it draws
40 watts of power ?
How long will it last ?
