Two students are playing on a swing set. Student 1 is leaning back and extending her legs as she moves upward. Student 2 is sitting on the swing with his feet on the ground. Which statement describes how position and work are related in this picture? (3.6B)

• Both students are doing work even if only one student is changing position.

• Student 1 is changing position because work is being done on the swing.

• Work done by Earth's gravity prevents Student 2 from changing position.

• Work is being done on both students by the swings because one swing is changing position.

The two pictures show part of an investigation. A magnet, a book, and a paper clip are on a sheet of lined paper. In Picture 1 a student slides a magnet closer to the book. The student holds the book still in both pictures. Which statement about this investigation can be supported by the result shown? (3.6B)

• Work was done on the magnet, the book, and the paper clip.

• Work was done on the magnet and the paper clip only.

• Work was done on the magnet and the book only.

• Work was done on the magnet only.
