Rolling is easier than sliding.

Rolling and sliding are two different types of motion. Rolling is the motion of an object that rotates around its own axis while moving forward, whereas sliding is the motion of an object moving over a surface without rotation.

There are several reasons why rolling is generally considered easier than sliding:

1. Friction: Rolling involves less friction compared to sliding. When an object rolls, only a small portion of its surface comes in contact with the ground, resulting in less resistance. On the other hand, when an object slides, the entire surface is in contact with the ground, leading to greater friction and making it harder to move.

2. Smoothness: Rolling motion is generally smoother than sliding. When an object rolls, it moves in a more controlled and stable manner, as the rotation helps distribute the weight evenly. Sliding, on the other hand, can be less predictable and may involve sudden stops or jerks, especially if the surface is uneven or rough.

3. Energy efficiency: Rolling requires less energy compared to sliding. Due to the reduced friction, less force is needed to initiate and maintain the motion of a rolling object. This makes rolling a more energy-efficient way of transportation. Sliding, on the other hand, requires more force and energy to overcome the higher friction and maintain the motion.

4. Stability: Rolling provides better stability compared to sliding. The rotation of a rolling object helps in maintaining balance and prevents tipping or falling over. Sliding, especially on inclined surfaces, can be less stable and more prone to accidents or loss of control.

In conclusion, rolling is generally considered easier than sliding due to factors such as lower friction, smoother motion, energy efficiency, and improved stability.
