Force, Mass, and Acceleration

Procedure

Read and complete the lab safety form and follow the procedure below.

1. Use a large balance to find the mass of this science book.

2. Tape a paper clip to your textbook so that the paper clip is just over the edge of the book. Use the paper clip to hook a spring scale to the book.

3. Pull the book across the floor or a table at a slow but constant velocity. While pulling, read and record the force on the spring scale.

4. Repeat step 3 two more times, once accelerating slowly and once accelerating quickly.

5. Place a second book on top of the first book and repeat steps 3 and 4.

Think Critically

6. How did adding the second book change the results? What does this show about the relationship between force and mass?
