What is the force that resists the motion of one surface across another?
it is the frictional force or force of friction that resists the motion of one surface over the another. but, interestingly, it is the force which helps us to walk, to swim... aman gupta
Is friction a contact or non contact force?
friction is a contact force
Why is it easier to pull a box across a surface with an upward angle then push a box across a surface with a downward angle?
Push a box across a surface with a downward angle because gravity is helping.
What is the tightness across the surface of water is called?
"surface tension"
The type of fog that results when moist air moves across a cold surface is?
Advection fog results when moist air moved across a cold surface. When moving across a cold surface, the air is cooled to its dew point.

What is the force that resist the movement of one surface past another surface is called?
A force that resists motion of one surface across another surface is called FRICTION(or FRICTIONAL FORCE)
Is friction a contact or non contact force?
friction is a contact force
Why do cell membranes have convolutions?
To increase surface area, allowing greater contact area for 'transport' of nutrients (movement of substances across the membrane).

Push a box across a surface with a downward angle because gravity is helping.

How does sandpaper slow thing down?
All materials have a property called the coeffecient of kinetic friction. When this property is high, a higher friction force resists the motion of objects across the surface. Sandpaper has a higher coefficient of kinetic friction as compared to something like ice. This is because ice is smooth whereas the surface of sandpaper is very rough which increases the friction it causes.
Do you have to overcome rolling friction when you slide a bag of groceries across the countertop?
If the bag is sliding across the countertop (i.e., the same surface of the bag is always in contact with the counter), then no. Rolling friction is only relevant when the surface of an object in contact with the surface it moves across always changes.
Is a boat sailing on the ocean is an example of rolling friction?
No, it is not. Rolling friction occurs when a round object rolls across a surface. A boat on the ocean is not in contact with any solid surface. Instead of rolling friction the boat is subject to drag.
Water flowing downhill across the surface of Earth is called?
Water flowing downhill across the surface of the Earth is called runoff.
Large bodies of ice that move across earth's surface?
Large bodies of ice that move across the Earth's surface are glaciers.
The type of the fog that results when moist air move across a cold surface is?
Advection fog results when moist air moved across a cold surface. When moving across a cold surface, the air is cooled to its dew point.
