Discovered Hements Rin and Po 6. Quantum Theory of linenty 7. Determined the charge A mass of an electron 8. Gold Foil Experiment Mom is mostly empty space) Discovered the nucleus. 9. Discovered that electrons move around the nucleus in orbits called electron shells 10. Arranged the periodic table by atomic number instead of mass number 11. Contributed to creation of Quantum Mechanies; pioneer in the theory of crystals; won Nobel Prize in 1954 for his work in interpretation of the wave function first proposed in 1926. 12. All moving objects have wave-like behavior. Matter shows properties of both wave and particles 13. Pauli exclusion principle 14. Discovered the neutron 15. Discovered nuclear fission 16. Father of nuclear chemistry 17. Discovered nuclear fission with Otto Hahn and help from Lise Meitner 18. A German physicist that speculated that there was no real certainty in where an electron was, and only tendencies. This broke down Newton's dependable laws to only probabilities. 19.

4. NASA wants to measure X-Rays but only have equipment that can measure Gamma Rays. Lesson NASA has to develop a new piece of equipment that detects difference wavelengths. Does NASA have to develop a new piece of equipment that detects longer or shorter wavelengths? Explain. __ 5. What is the order of electromagnetic waves from shortest wavelength to longest? __ 6. What is the order of electromagnetic waves from highest frequency to lowest frequency? __ 7. The sun produces all of these rays. Why do you think that not all of these rays are not hitting earth's surface? Explain your answer. __

3. What is the difference between a law about gravity and a theory about gravity?(14 Points) A law says objects fall, while a theory of gravity explains the pull between masses A theory of gravity is less scientific than a law of gravity A theory about gravity is just a guess, while a law is proven forever A law describes what gravity does , while a theory ex- plains why gravity works

When would a swimmer have the most potential energy due to her position? A. Kicking off the side of the pool during a race B. Touching the bottom of the pool C. Traveling across the pool using the backstroke D. Sitting on the highest diving board at the pool

Which statement best describes the meaning of two intersecting lines on a position-time graph? The two objects are at a common position at different times. The two objects are at different positions at the same instant in time. The two objects have the same position at that point in time.

Learning Log: How do you think you get something to have more kinetic energy?

Multiple energy that moves in waves. the form of energy that actually does work. energy that flows between objects with different temperatures. movement of ions or electrons.

1. If two shopping carts of equal mass are pushed with different forces, how will their motion be affected? 2. If two shopping carts with different masses are pushed with the same force, how will their motion be affected? 3. If two shopping carts have different masses, but the same acceleration, what can be said about the forces acting on them? 4. How much force was applied to a 10 kg shopping cart if it accelerated at a rate of $2m/s2$
