Pavement is smoother and harder than grass, providing a rougher surface for tires to grip onto, thus creating more friction. Grass has a softer and uneven surface, resulting in less traction and lower friction compared to pavement.
friction: the force that resists relative motion between two bodies in contact.
The force responsible for the painful difference between sliding on grass and sliding on pavement is primarily friction. Grass has more resistance and provides a softer landing surface, reducing the impact force compared to the harder and more abrasive surface of pavement. This difference in friction and surface roughness affects how energy is dissipated during a slide, leading to a less painful experience on grass compared to pavement.
Pavement will heat up faster than grass on a hot day because pavement absorbs and retains heat more effectively than grass. Grass tends to have a higher albedo, meaning it reflects more sunlight and absorbs less heat compared to pavement.
On wet pavement, the presence of water reduces the friction between the tires and the road surface, making it more slippery. This is because the force needed to overcome static friction (needed to start moving) is less than the force needed to overcome sliding friction (needed to maintain motion). As a result, it is easier for a vehicle to slide or skid on wet pavement compared to dry pavement.
Grass has more friction than ice because grass has a rougher texture and more surface area for objects to grip onto, creating more resistance when moving over it. Ice is smoother and has less friction because it has a low coefficient of friction, making it easier for objects to slide over its surface.
Dry pavement creates more friction than ice pavement because when surfaces are dry, there is more contact between the tires and the road, leading to increased friction. On the other hand, ice has a low coefficient of friction, causing tires to slip more easily since there is less traction between the ice and the tires.

Well... An icy pavement doesn't have a lot of friction. Unless you have special shoes used for walking on ice that will give you better grip. Grass has a ton more friction than ice. But if you wanted to get even better grip, use cleats.
Grass. This is because carpet (grass or soil) has more friction than a smooth surface like tile (concrete).

Yes there is. Because if it is in the grass it will soak into the soil. :)
Pavement will heat up faster than grass on a hot day because it has a lower albedo, meaning it absorbs more solar energy. Grass has a higher albedo and also benefits from transpiration, which helps to cool the surface.

Ice has more friction. Ice has hard ridges that would collide with other ridges easier to make more friction. Grass on the other hand doesn't have a lot of ridges and grass is very bendable.
Yes, sliding friction creates more thermal energy and wears down the two surfaces quicker than rolling friction.
