  1. Agnes and Katrina Homework

  2. Graph/Info for Q1-Q3 • The following data was collected when a golf ball was dropped from a height of 50 cm onto a ‘rigid’ foam block.

  3. Q1 • The vibrations recorded when the golf ball was dropped onto the rigid foam are very different from the vibration signature of the lab table. • Compare the data shown above for the foam block to the data you collected. (must use data collected from part D of the lab)

  4. Q2 • Did any of the vibration signatures you collected resemble the ones collected from the rigid foam?

  5. Q3 • Did any of the surfaces you investigated have vibration signatures very different from the vibration signature of the foam block? • If so, what was different: the period of the motion? Was the duration of the motion different? Was the height of the vibration different?

  6. Q4 • Do you agree or disagree with the following statement? Explain your answer A water “particle” and a water “molecule” are the same thing.

  7. Q5 • Do you agree or disagree with the following statement? Explain your answer Heat energy is the kinetic energy of the randomly moving particles in a substance.

  8. Q6 • Do you agree or disagree with the following statement? Explain your answer The tiny particles that make up all matter can be seen under a high school microscope

  9. Q7 • Do you agree or disagree with the following statement? Explain your answer Energy can be transferred through solids because the particles are held together by flexible connections.

  10. Q8 Why do you smell a person perfume or cologne from across the room? Explain your answer in terms of the Kinetic theory of matter.

  11. Q9 List the main ideas of the kinetic theory of matter:

  12. Q10 • How does the amount of energy an object’s atoms have determine the object’s state of matter

  13. Q11 List the 4 states of matter, from the state with the most thermal energy to the state with the least.

  14. Q12 • How do we know if the atoms of an object in our hand have a large amount of energy?

  15. Q13 • Using the Kinetic theory and the definition of matter explain why pressure of a gas in a bottle increases when its temperature increases.

  16. Q14 • Use kinetic theory of matter to explain what happens to a balloon when taken from a very warm house out into a snowstorm.

  17. Q15 • What is the main difference between KE and heat energy?

  18. Q16 • Why is the KE of the rain drops or the sea surge in a hurricane to be so feared by those in their path? Answer in terms of work.
