(c) static, sliding, rolling Friction comes into play while irregularities gift withinside the surfaces of gadgets in touch get interlocked with every other. Static friction comes into play while we strive to transport an item that is at rest. Sliding friction comes into play while an item slides over the floor of some other item. In sliding friction, the time given for interlocking may be very small. Hence, interlocking isn't always strong. Therefore, much less pressure is needed to triumph over this interlocking. Because of this reason, sliding friction is much less than static friction. Similarly, the vicinity of touch in case of rolling friction is smallest in comparison to static or sliding friction. This vicinity of touch modifications steadily due to rolling. Hence, rolling friction is lesser than each static and sliding friction. Thus, the appropriate sequence is - static, sliding, rolling.
