A trolley is pushed with a force that causes it to move a certain distance. It moves in the direction it is pushed
Which row in the table represents the combination of force and distance that means the
smallest amount of work is done on the trolley?

answer:

When objects slow down or stop moving, it's always due to an outside force, like friction or air resistance. Friction occurs when two objects rub against each other. As a skier moves over the snow, the contact between the skis and the snow creates sliding friction
