How do droplets pin on solid surfaces?
The droplet first rests on a solid surface that contains nano-scale surface defects. To obtain the static friction force , a series of lateral body forces are exerted on the droplet, until static friction occurs at the surface defect.

When one solid surfaces slide over another?
Sliding Friction – occurs when one solid surface slides over another. Rolling Friction – occurs when an object rolls over a surface. Fluid Friction – occurs as an object moves through a fluid. Gravity – force that pulls objects toward each other.
What occurs when solid surfaces slide over each other?
Friction is the resistance to motion that occurs when one solid surface slides over another. The sliding occurs due to a force being applied in the direction of motion.
Why do liquid drops take different shapes on solid surfaces?
Due to surface tension, surface tries to minimize its area. As sphere has the minimum surface area among all geometrical shapes thus, liquid drop becomes spherical.
