You wish to move a heavy box on a rough floor. The coefficient of kinetic friction between the box and the floor is 0.9. What is the best way to reduce the force of friction between the box and the floor while the box is moving? A. Push or pull the box with a force parallel to the floor. B. Pull the box with a force directed up at an angle of 30° from the horizontal. C. Push the box with a force directed down at an angle of 30° from the horizontal. D. The coefficient of friction does not change so the force of kinetic friction acting on the block must be constant E. Both B and C result in the same force of friction.

What is kinetic friction give an example?

If two surfaces are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, friction slows a hockey puck sliding on ice.

What are kinetic and static friction?

In static friction, the frictional force resists the force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object.
