Billy rolls a toy truck filled with marbles across the kitchen floor. He then dumps the marbles before rolling it back to his starting location. How would the speed of the truck MOST LIKELY change on the way back?

• The speed would increase due to friction

• The speed would increase due to a change in mass

• The speed would decrease due to a change in mass

• The speed would decrease de to a change in gravity
