Elements refer to the different types of atoms that exist on the periodic table, but they are not the smallest parts of atoms themselves.

Explanation
Rolling a stone up a sloping road requires less work compared to lifting it vertically upwards because in rolling, the force exerted is applied over a longer distance. This means that the work done is equal to the force multiplied by the distance. As the distance is longer in rolling, the force required is less compared to lifting it vertically. Therefore, less work is done in rolling the stone up a sloping road compared to lifting it vertically.
