Work vs. effort: Why is it easier to roll a stone up an inclined road than to lift it vertically? Analyze in terms of work done and applied force (mechanical advantage of an incline). Choose the correct option.

Difficulty: Easy

• Because less work is done on the incline than lifting the same height
• Because the stone loses mass on the incline
• Because the applied force is smaller over a longer distance; total work (mgh) is the same
• Because gravity is weaker along a slope
