Miss Thompson is trying to move a heavy box filled with Christmas decorations. Why is the box hard for Miss Thompson to move?

• The box has a lot of friction so not much force is required.

• The decorations have a lot of mass so a large force is required.

• The box has a little friction so a large force is required.

• The decorations have a little mass so not much force is required.
