This food web demonstrates the interconnection between living things in a complex ecosystem.
This detailed food web depicts a more complex flow of energy in a forest ecosystem.
This simple food web depicts the flow of energy in a forest ecosystem.
Electric potential difference causes electric charges to move from one battery terminal, through the wire, to the other battery terminal.
When charges flow through a wire or other material, an electric current is created. Electric current involves the flow of charges.
If a short circuit occurs, the charge could flow into the shell of the appliance and the appliance could shock someone touching it.
If a proton and electron come close, they attract each other.
An electrical charge occurs as the opposite charges attract between the bottom of the cloud and the ground below. The lightning bolt we see is an example of electrical discharge.
Inside a large storm cloud, water droplets and other particles are moving around very quickly, creating static electricity.
An electric motor consists of a coil of wire, called an armature, which is attached to a shaft that spins between the poles of a magnet. As electric current flows through the coiled wire, the magnet pushes one side of the coil up and the other side down.
A galvanometer consists of a coil of wire wrapped around a piece of iron that is connected to a needle. This coil of wire spins between the poles of a magnet. When connected to a circuit, the current flows through the wire of the magnetic field.
Model of generator powered by water. The water turns the turbine, which spins the crank shaft that is connected to this wheel of magnets. Coils of wire surround the electromagnets. The electromagnets induce a current in the surrounding coil of wire.
Depicts lines of magnetic force around a current-carrying wire. Electric current flowing through a wire produces a magnetic field. The lines of magnetic force are in a circular shape around the wire.
In a step up transformer a smaller amount of voltage enters the primary coil, and a larger amount of voltage leaves the secondary coil.
A transformer is composed of two coils of wire - a primary coil and a secondary coil. The coils are wrapped around a metal structure. When an alternating current enters the primary coil, a magnetic field is created.
Depicts helium atoms in a balloon.
This animation depicts bonds between atoms. Within bonds is a certain amount of energy referred to as chemical energy.
Matter is composed of atoms.
Energy released from the nucleus is the most concentrated form of energy.
Two models of the nucleus of an atom, where nuclear energy is stored.
