How do different weights affect friction?
Friction is a resistance force imparted on an object sliding across a surface where the force is directly proportional to the WEIGHT of the object. The heavier the object that is moving across the surface the higher the frictional forces.
What is the friction that exits between a surface sliding on another surface is called?
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
What force is required to push an 600N object?
The force required to overcome friction = the coefficient of friction x the reactive force (as in, the force the object exerts on the surface you want to move it over). So, you have to know the coefficient of friction, and simply times it by 600 in this case to know the force required. Oddly, once friction has been overcome, the required force drops slightly to keep it moving.
What causes more friction?
If an object is moving on the same surface the friction is the same throughout. However, more friction is caused by a rougher surface and less friction is caused by smoother surfaces.
The force that opposes the motion of an object moving on a surface?
Friction.

What is kinetic friction and static friction?
Friction is the resistance to movement of an object pressing/resting/moving on a surface. It's not intuitively obvious but the standing still friction and moving friction are different. Assume you have a block of wood resting on a tabletop. The amount of force required to make the block begin to move (static friction) is greater than the force required to keep it moving (kinetic friction) after it has begun to move.
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.

If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.

Give a long introduction of friction and its types?
the four types of friction are static friction,sliding friction,rolling friction,and fluid friction Static friction is friction between two solid objects that are not moving relative to each other. Fluid friction is with any kind of liquid or glass. sliding friction is when a surface slides on another surface. Rolling friction is when you are moving with wheels.
What is friction affected by?
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.
Is it true that if you slide a bag of groceries along a countertop you must overcome rolling friction?
Rolling friction results from momentary attractions between a rolling object and the surface it is rolling on, so as long as the same surface of the bag is always facing the surface, as is usually true for sliding, there is no rolling friction to consider.However, for sliding, there are two different values for friction: the static value, which is how much force must be applied to a resting object to start moving it across a surface; and the dynamic value, which is how much force must be applied to a moving object to make it keep moving with the same velocity.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
Why rolling friction is less than sliding friction?
Rolling friction is the force of friction between two surfaces when one surface rolls over another.Sliding friction is the force of friction between two surfaces when one surface is moving on another.
