What type of force occurs when two surfaces slide past each other?
Which of the following is not true about Kinetic friction?
If a block at rest on an inclined plane begins to slide when the incline angle is increased to 30 degrees, what is the coefficient of static friction between the block and the plane?
If two billiard balls collide on a frictionless table and one ball comes to a complete stop, what must be true about the motion of the other ball after the collision?
If the coefficient of static friction between a block and an inclined plane is increased while keeping all other factors constant, how does this affect the minimum angle at which the block begins to slide?
What effect would using a heavier sled have on kinetic energy at the bottom of an icy hill assuming no energy losses and that all other conditions remain identical?
A block of mass is being pushed up a frictionless incline with an angle from the horizontal; which of the following represents the net force acting on the block if it is moving up the incline at a constant velocity?
