Grazing can have both positive and negative effects on soil health. Positive effects include increased nutrient cycling and soil aeration from animal trampling. However, overgrazing can lead to soil compaction, erosion, and decreased organic matter levels, which can degrade soil quality over time. Rotational grazing practices can help mitigate the negative impacts and improve soil health.

Over grazing by domestic livestock.
Yes, guinea pigs are grazing animals, and they need constant supply of grass hay. When grazing, they prevent their teeth (which are growing constantly throughout life) from over growing. You can hear guinea pig grazing sound on the provided link.

Grazing your knees and hands when falling over and sliding on a hard surface is caused by friction with the ground. A spacecraft returning to earth will heat up to red hot due to friction with the atmosphere. These are just two bad effects of friction. But, there are good effects, too. Friction from your vehicle or bicycle brakes will bring you to a stop! Friction from your tyres and the road surface will prevent you from skidding.
Over-grazing and cutting down trees for fuel
By "Free Grazing" you mean Continuous Grazing, I assume. Yes they can, because they pick the best plants to eat, and keep eating them as they grow back, decreasing the population and vigour of these desirable species, and enabling the less desirable species to take over.
