7. Is there work being done by the following scenario: Mrs. Taylor is a waitress at a restaurant. She carries food across the room. She gets to a customers table and lowers their food onto the table. Is Mrs. Taylor doing work?

• No, because Mrs. Taylor doesn't bring the tray up or down.

• I don't know and I need to be coming to tutorials.

8. Is there work being done by the following scenario: Mrs. Taylor pushes an object off the table and the object free falls to the ground. Is there work being done?

• No, because the object is not doing work. Gravity is not acting
• Yes, because gravity is acting on the book.
• I don't know and I need to be coming to tutorials.
