Down
- 1. the energy that an object has because of the position condition or chemical composition of the object
- 3. the process of creating a current in a circuit by changing a magnetic field
- 4. a push or a pull exerted on an object in order to change the motion of an object, force has size and direction
- 5. the sum of an object's kinetic energy and potential energy due to gravity or elastic deformation does not include chemical energy or nuclear energy
- 6. a material in which charges cannot move freely
- 8. a coil that has a soft iron core and that acts as a magnet when a electric current is in the coil
- 10. an element or compound that conducts electric currents better than an insulator does but not as well a conductor does
- 12. the force of attraction or repulsion generated by moving or spinning
- 14. force that resists the start of sliding motion between two surfaces that are in contact at rest
- 17. any region in which a physical force has an effect
- 18. a material in which charges can move freely
- 19. a force parallel to the velocity of the flow it opposes the direction of an aircraft and in combination with thrust determines the the speed of the aircraft

- 22. any material that attracts iron or materials containing iron
- 25. a fundamental property of that leads to the electromagnetic interactions among particles that make up matter
