Gravitational potential energy stored in the water reserved in a dam becomes useful to generate electricity.
They are useful in situation with many variables and can create useful digital images and can represent how a system or process works or.... all of the above....
The net output of useful work is (weight) times (gain in height) = 2,000 newton-meters = 2,000 joules.The rate of doing the work, and adding to his gravitational potential energy,is (2,000/40) = 50 joules per second = 50 watts.He certainly had to generate and expend more power than that in order to accomplish the climb.But most of the energy he expended went into heating his muscles and the rest of his body.50 watts is the power that went into the useful part of hoisting his weight to a position of fivemeters higher than where he started.
Adding or subtracting fractions requires the use of a common multiple. It is rare that the LEAST common multiple is required - it is useful to keep the numbers small and manageable.

it is the energy of position and most objects have gravitational potential energy, all they need is a height, and to NOT have a spring/elastic
You lift a beer can a foot off the table, thus imparting gravitational potential energy to each preciousgolden drop of liquid in the can. You then tilt the can, positioning its orifice directly above the waiting stein.The liquid gives up its gravitational potential energy while falling from the can into the glass below.Upon impact with the glass, the gravitational potential energy has become kinetic energy, which is usedto generate the bountiful and luxurious head.
For example, in a hydroelectric power plant, where it is converted into electricity.For example, in a hydroelectric power plant, where it is converted into electricity.For example, in a hydroelectric power plant, where it is converted into electricity.For example, in a hydroelectric power plant, where it is converted into electricity.
First look at what it is used for then decide if that is dangerous. Its used to make car batteries, those are not too dangerous, but somewhat dangerous. Sulphuric acid is both useful and dangerous. It is like asking whether a dam is useful or dangerous. It is both useful and it does present a danger. It is the most used acid in industry. However, it can literally suck water out of your skin if concentrated and if not it can cause severe burns.
Snakes don't help humans..but they are useful for entertainment..but are dangerous.
potentially - with a possibility of becoming actual; "he is potentially dangerous"; "potentially useful"1. Capable of being but not yet in existence; latent: a potential problem.2. Having possibility, capability, or power.3. Grammar Of, relating to, or being a verbal construction with auxiliaries such as may or can; for example, it may snow.
oxygen is th most useful gas
It is useful!
it is not its made of dangerous gas
