Whats diff between crawling motion and rolling motion and why cant we use crawling action instead of rolling in locomotives?

Question

Accepted Answer

Crawling and rolling are different locomotive motions. Crawling is not efficient for locomotives due to friction and stability issues.

Crawling involves dragging the body along the ground using limbs, while rolling involves rotating the body along a surface.
Crawling is not efficient for locomotives due to the high friction between the body and the ground, which requires more energy to move.
Rolling is more efficient for locomotives as it reduces friction and allows for greater stability.
Examples of rolling locomotion include wheels on a car or train, or the rolling motion of a ball.
Crawling is more commonly used by animals with a low center of gravity, such as snakes or lizards.
