- 1. Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
- 7. downward movement under the force of gravity only.
- 8. in electricity generation, a generator is a device that converts motive power into electric power for use in an external circuit
- 12. An electrical insulator is a material in which electric current does not flow freely.
- 13. Magnetic field is a vector field that describes interaction between moving electric charges (that is, electric currents), and magnetic materials
- 14. strength or energy as an attribute of physical action or movement.
- 16. the curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution.
- 19. magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.
- 20. a tendency to do nothing or to remain unchanged.
- 21. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
- 24. In physics, a field is a physical quantity, represented by a number or another tensor, that has a value for each point in space and time.
- 25. An electric motor is an electrical machine that converts electrical energy into mechanical energy.
- 26. Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field.
Down
- 2. Electromagnetism is the physical interaction among electric charges, magnetic moments, and the electromagnetic field.
- 3. Static friction is a force that keeps an object at rest.
- 4. pull (someone or something) along forcefully, roughly, or with difficulty.
- 5. a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.
- 6. a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.
- 9. In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.
- 10. a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
- 11. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
- 15. Mechanical energy (kinetic energy or potential energy) is the energy of either an object in motion or the energy that is stored in objects by their position
- 17. A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.
- 18. each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically.
- 22. The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
- 23. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
