Question 18

A student has two 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?

Accepted Answer

Box A will require more force, because the mass is greater than the mass of Box B.

Answer

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

Answer

Box B will require more force, because more ping pong balls can fill a box.

Answer

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