A ball is rolled on sand, on a cemented road and on an ice platform. In which of these cases will it move the farthest?
Ice
When a ball is rolled along a surface, the frictional force opposes its motion. The frictional force is least in the case of ice as compared to sand and road since ice has a smooth surface compared to the other two. Thus, the ball will travel the farthest in the case of ice.
