If a force is required to pull a 20 kg box across a carpeted floor what is typically true about another force required to pull the box across the ice at a rink?
Pulling a box across ice requires less force than pushing the same box across carpet. This is due to the amount of friction between the carpet and box and the lack of friction between the ice and the box.
Which form of friction is the one that deals with objects that are already moving?
Kinetic friction is the form of friction that deals with objects that are already in motion. Kinetic friction opposes the motion of an object as it slides or moves across a surface.
The force that opposes the motion of an object moving on a surface?
The force that opposes the motion of an object moving on a surface is called friction. Friction occurs due to the interaction between the surfaces of the object and the surface it is moving on, which creates resistance to motion.
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.
Would there be more friction between A snowboard gliding across snow or moving a box on carpet and why?
There would be more friction between the box moving on carpet. This is because the rough surface of the carpet creates more resistance and friction compared to the smoother surface of the snow. Snowboards are designed to glide easily on snow due to the reduced friction between the smooth base of the snowboard and the snow.
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.

When a body slides over a surface the kinetic friction and static friction related as?
The kinetic friction is the force that opposes the motion of an object as it slides over a surface, while the static friction is the force that prevents an object from moving when at rest on a surface. Kinetic friction is generally weaker than static friction for a given surface.
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.

How does friction affect the amount of torque required to move an object?
Friction increases the amount of torque required to move an object. This is because friction creates resistance between the object and the surface it is moving on, making it harder to overcome and requiring more torque to initiate and maintain movement.
What is the force that opposes motion when moving objects over a surface called?
The force that opposes motion when moving objects over a surface is called friction
When an object is pulling across a level surface at a constant velocity what force is the pulling force equal to?
When an object is moving across a level surface at a constant velocity, the pulling force is equal to the force of friction acting in the opposite direction. This force of friction is equal in magnitude and opposite in direction to the pulling force, resulting in a balanced situation where there is no acceleration.
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.
What is the relationship between the keyword block and friction in the context of physics?
In physics, the keyword block is a term used to describe an object that is in contact with a surface and experiencing friction. Friction is the force that opposes the motion of the block when it is trying to move across the surface. The relationship between the keyword block and friction is that the frictional force acts on the block to prevent it from sliding or moving easily on the surface.
