Across 4. GPE = Mass x Gravity x Height 5. A magnet is an object that produces a magnetic field in the area around it. 8. Larger objects can be given a positive charge by removing electrons. 9. the basic unit of a chemical element. 14. Potential Energy is energy stored because of the position of an object. 15. Power is the rate at which work is done. How quickly does energy get transferred. 16. Particles can either be positively or negatively charged. 17. Permanent magnets are made up of small regions called magnetic 18. The net force on an object is the vector sum of all the forces acting on an object.

Down 1. Larger objects can be given a negative charge by adding electrons. 2. Anything that pushes or pulls on an object 3. For every force, there is an equal and opposite force. 4. When energy is conserved, the initial energy equals the final energy. We don’t lose any energy. 6. An object at rest will stay at rest 7. The net force on an object is proportional to the acceleration of that object. 10. A _is the north or south end of a magnet where the force is the greatest. 11. a compound formed by ions bonding together through electrostatic forces. 12. wo students both push identical boxes with the same force for the same distance as shown. 13. A _ is a field of force present around a magnet which exerts a force on other magnets, magnetic materials, or charged particles
