The triboelectric effect causes an electrostatic charge to build up on the fur due to the cat's motions. The electric field of the charge causes polarization of the molecules of the styrofoam due to electrostatic inductionresulting in a slight attraction of the light plastic pieces to the charged fur. This is also the cause of static cling in clothes.
Particle that has no charge Electron: A material that shows strong magnetic properties. Making and Changing Magnets Magnets can be made, destroyed or broken apart. Magnet made from a material that keeps its magnetism for a long time Magnetic Earth: Just like a bar magnet, Earth has a magnetic field surrounding it 2 magnetic poles Magnetic Declination: Since Earth produces a strong magnetic field, Earth itself can make magnets out of ferromagnetic materials.
Charges that are the same repel each other. Charges that are different attract each other. Law of Conservation of Charge: When a negatively charged object and a positively charged object are brought together, electrons transfer until both objects have the same charge.
A conductor transfers electric charge well. An insulator does not transfer electric charge well. First, circuits have devices that are run by electrical energy.
Second, a circuit has a source of electrical energy. Third, electrical circuits are connected by conducting wires.
You can calculate power by multiplying voltage by current. The total amount of energy used by an appliance is equal to the power of the appliance multiplied by the amount of time the appliance is used.
The field can be turned on or off, have its direction reversed, or have its strength changed Solenoid: Electrical Energy and Motion: Induction of Electric Current: An electric current is induced in a conductor when the conductor moves through a magnetic field.
A transformer is a device that increases or decreases voltage. How to cite this page Choose cite format:Application of physics concepts and principles for designers such as architects, interior designers, and engineers using focused problem-solving in work-groups.
Topics selected from mechanics, sound, thermodynamics, optics, electricity, magnetism, and modern physics. This simulation provides a realistic virtual mass-and-spring laboratory. Students can explore spring motion by manipulating stiffness of the spring, the hanging mass, the initial pull, damping (friction) and gravity.
