Objects like ice or polished metal have very low friction due to their smooth surfaces. They also have low friction coefficients, meaning they require little force to move across a surface.
Rolling friction produces the least amount of friction compared to other types of friction like sliding or static friction. This is because rolling friction involves an object rolling smoothly over a surface with minimal resistance.
The amount of friction divided by the weight of an object forms a unitless number called the coefficient of friction. It represents the relationship between the force of friction and the normal force acting on an object. A higher coefficient of friction indicates greater friction between the surfaces.
The amount of friction acting on an object on a solid surface can be influenced by factors such as the roughness of the surface, the weight of the object, the normal force pressing the object onto the surface, and the presence of any lubricants between the object and the surface. Additionally, the coefficient of friction between the surfaces in contact also plays a significant role in determining the amount of friction.
Friction acts as a force that opposes the motion of an object, causing it to slow down. The greater the amount of friction present, the more it will impact the speed of the object.
A smooth, slippery surface like ice or Teflon typically has the least amount of friction. This is because these surfaces have very low coefficients of friction, allowing objects to slide easily with minimal resistance.
Neglecting friction, its speed will grow with the least acceleration. Considering friction, it may not move at all.

No, an object's weight does not directly affect the amount of friction between the object and the surface. Friction is determined by the nature of the surfaces in contact and the normal force acting between them, which is influenced by weight but is not directly proportional to it.
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.
coefficient
Friction opposes the motion of an object, reducing its speed or causing it to come to a stop. The amount of friction depends on the surfaces in contact and the force pressing them together. More friction means it's harder for an object to move.
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
