he may have worms. or maybe its just an itch. but if he continuously does it. see a vet or get worm killer/ prevention.
Sliding your hands together is an example of sliding friction.
Friction between the desk and the floor acts as an unbalanced force to stop the desk from sliding. As the desk moves, the force of friction opposes the direction of its motion, eventually bringing it to a stop.
The force that slows you down as you slide across the floor is primarily kinetic friction. This force arises due to the interactions between the surfaces of the sliding object and the floor, leading to resistance that opposes the motion.
This would be sliding friction and it could happen when:run on the floor
first you ejaculate onto the football, rub it around in your hands a bit and slide it across a smooth floor and WA LA you have sliding friction on a football XD
The force of friction acting on a crate sliding across the floor is equal in magnitude but opposite in direction to the force applied to move the crate. It depends on the coefficient of friction between the crate and the floor, as well as the weight of the crate.
Some simple examples of sliding friction include dragging a heavy box across the floor, sliding a book along a desk, or rubbing your hands together. In each case, the resistance encountered when trying to move one surface over another is due to sliding friction.
An example of sliding kinetic friction is pushing a box across the floor. As the box moves, there is friction between the box and the floor opposing its motion. This friction force must be overcome by applying a force in the direction of motion.

The predicate in this sentence is across the floor. :)
To calculate the force of the box being slid across the floor, the person needs to know the mass of the box and the acceleration of the box. Using the equation F = ma (force equals mass times acceleration), the person can determine the force required to slide the box across the floor.
