Assuming the two surfaces are the same, the amount of friction is proportional to the mass of the object, so the heavier the rock the greater will be the frictional force.
Jill would need high friction on her hands and feet when climbing. This allows her to grip onto rocks or holds securely and prevent slipping. High friction helps her to move effectively and safely while climbing.
Friction slows down the motion of objects, so it does not cause them to move faster or fly higher. In fact, more friction can make it harder for objects to reach high speeds or heights.
When skiing, you need low friction to glide smoothly over the snow. High friction would cause you to feel resistance and make it difficult to slide across the surface. A low friction surface allows you to maintain control and move efficiently.
Friction is a force that opposes the motion of objects in contact with each other. It arises due to the irregularities on the surfaces of the objects, causing resistance when they slide or rub against each other. This resistance force acts in the opposite direction to the motion, affecting the movement and speed of the objects.
A high coefficient of friction indicates that there is strong resistance to sliding between two surfaces in contact. This means that it would take more force to move the surfaces against each other.
You need high friction on your climbing shoes when making contact with the rock surface, especially on small holds or slippery surfaces. High friction helps you to maintain grip and stability while ascending the rock face.

Rock avalanches can move at great speeds due to the combination of loose rock material and their steep slopes. When the slope fails, the rocks can accelerate quickly due to gravity, generating high speeds as they travel downhill. The fast movement of rock debris in avalanches is also attributed to the lack of friction and resistance as it flows over the ground.

Friction on sand is typically high due to the rough and uneven texture of sand grains. This rough surface creates resistance when objects move across it, resulting in a higher frictional force.
Surfaces such as carpet, rubber, sandpaper, and rough concrete tend to produce high friction due to their rough textures that create resistance when objects slide or move across them.
Friction is high on a carpet.
The force needed to move a pencil across a desk would depend on the friction between the pencil and the desk surface. If there is low friction, only a small force would be needed. If there is high friction, a greater force would be required to overcome it.
