7. Explain whether an object can have potential or kinetic energy at the same time. Be specific in your explanation and provide an example to back up your reasoning.
8. Is it possible for an object at rest to have energy? Explain your reasoning.
17. What is the difference in the gravitational potential energy of a 7.75 kg book that is 1.5 m above the ground and a 9.53 kg book that is 1.75 m above the ground?
(a)
18. A 10 kg bag of groceries is sat on a counter 1 m above the floor. How much gravitational potential energy does the bag have?
(a)

Match the following terms with the correct scenarios
this type of heat transfer causes you to burn your hand when you touch a hot pan on the stove
Conduction
this type of heat transfer is how water is heated to boiling
Convection
this type of heat transfer is how the sun warms the earth
Radiation
a coat that keeps you warm in the winter time is an example of this
Insulator
metals allow heat to pass through them easily which makes them a good example of this
Conductor
44. You have a 5 gallon bucket full of water, and your friend has a 75 gallon bathtub full of water. Which will require more energy to raise the temperature? Why?
45. Does a substance that heats up quickly have a high or a low specific heat capacity? Does a substance that cools down quickly have a high or low specific heat capacity? Explain both.
46. Conduction can occur between solids, liquids, and gases. EXPLAIN why solids and liquids are better conductors of heat than gases. Provide an example to prove your point.
