A student has 2 boxes that need to be moved. Box A is filled with heavy dishes and glasses. Box B is filled with ping pong balls. Both boxes are the same size.

Which box requires the student to use more force to move it? Why?

• Box A will require more force because the mass of the dishes are less than the ping pong balls.

• Box B will require more force because more ping pong balls can fill the box.

• Box A will require more force because the mass is greater in that box.

• Both boxes will require the same amount of force because the boxes are the same.

A Student has 2 boxes that need to be moved. Box A is filled with heavy dishes and glasses. Box B is filled with ping pong balls. Both boxes are the same size.

If the student used the same amount of force on boxes A and B, what would happen? Explain why?

• Box A would move farther than Box B because it has a greater volume.

• Box B would move farther than Box A because it has less mass.

• Box A would move farther because it has greater mass.

• Both boxes will move the same distance because they are the same size.

• glass and tile

• carpet and glass

• wood and tile

• glass and wood
