What is high in friction but is not useful?
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
How can friction be considered a force?
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.
Where does she need high friction if Jill is climbing?
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.
What are some things in the house that have high friction?
Rough surfaces like carpets, rubber pads, and textured flooring can have high friction in a house. Items like rubber stoppers, grippy jar openers, and velcro strips can also create high friction.
Which two surfaces would have the highest cofficient of friction?
Two rough surfaces with high friction coefficients would have the highest coefficient of friction. For example, rubber on concrete or sandpaper on wood would typically result in a high coefficient of friction due to the roughness of the surfaces.
