## 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

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?...
