Solved A student wants to explore the potential energy

Answer to A student wants to explore the potential energy. To explore the potential energy stored in a system of two magnets with like poles, bring the two like poles (both north or both south) closer together, because doing so increases the work done against the repulsive magnetic force, thereby increasing the magnetic potential energy.

Where do magnets get the energy to repel?

If I separate two magnets whose opposite poles are facing, I am adding energy. If I let go of the magnets, then presumably the energy that I added is used to move the magnets together again. However, if I start with two separated magnets (with like poles facing), as I move them together, they repel each other.

Energy science

Potential energy and kinetic energy. Although there are many kinds of energy in the world, they all fall into two broad categories: potential energy and kinetic energy.When energy is stored up and waiting to do things, we call it potential energy; "potential" simply means the energy has the ability to do something useful later on.

Can we harvest the energy of lightning? | HowStuffWorks

Third, the energy contained in a lightning bolt disperses as it travels down to Earth, so a tower would only capture a small fraction of the bolt''s potential. In the end, barring the development of a technology that could capture the energy from lightning before it strikes, it''s probably best to focus on other, more earthly sources of energy.

So no, using them for energy storage is not reasonable. There are still tasks were we need to store light coherently (or more precisely store the information that is encoded in the light) as in

Forms of energy

Mechanical energy is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored mechanical energy. Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together. Large amounts of energy can be released when the nuclei are combined or split apart.

How EPA Can Influence Light Pole Buying Decisions

The EPA of any light pole system varies depending on the angles, shapes, and sizes of the systems. Even the shape of the pole can change the EPA of a complete system. For example, square poles have a larger EPA than round poles. Poles with sharp corners create more drag than rounded fixtures and therefore have a higher drag factor.

Where does a permanent magnet get it''s energy from? :

Now the magnet does not, on its own, have "energy" in the sense relevant to the OP''s post (the magnetic field itself can be said to have energy, as mentioned in other posts, but that kind of overcomplicates the issue; the energy of a magnetic field is not "used up" when magnets attract because a bigger magnet is formed).

How Grid Energy Storage Works

Supercapacitors, even speedier than flywheels, store energy by separating charges. They''re "super" because they store more energy than traditional capacitors, but they work the same way. When there''s extra electricity, it can be used to push charges off of some metal plates and onto others, leaving some positively and others negatively charged.

Harvesting lightning energy

Since the late 1980s, there have been several attempts to investigate the possibility of harvesting lightning energy. A single bolt of lightning carries a relatively large amount of energy (approximately 5 gigajoules or about the energy stored in 38 Imperial gallons or 172 litres of gasoline). However, this energy is concentrated in a small location and is passed during an extremely short period of time (microseconds ); therefore, extremely high electrical power is invol

How do you store electricity as a charge?

We don't store electricity as charge, we store it as chemical energy in a battery because that's easier, cheaper and more useful. If you want to store light put the energy in a battery then use the energy to power an LED. @raptortech97: we can store charge temporarily in a capacitor and we can store a magnetic field temporarily in an inductor.

How do we store sun light?

So, may be, the very first thing that we need is to find such a media to store the sun light, as that hot gas containing atoms of rubidium or may be that should be some sort of a solid matter, and a second step is to create a sort of a convertor to transform that collected energy into a mechanical or electrical power.

Why is it hard to store light as light?

It's hard to store light as light because the most common way light interacts with matter is through absorption and emission, which is how mirrors work. However light rays can be bent by gravity, so it would be possible to arrange several massive stars in a way such that a light ray would move in a loop around the stars without energy loss.

Is lightning a viable energy source?

“And even if you had the right equipment set up, there’s no guarantee that lightning will hit it every second anyway.” When compared to other natural energy sources, lightning is definitely not as viable to harvest. Prof. Fletcher says solar and wind power are king when it comes to providing reliable, clean energy.
