Sliding Friction
Sliding friction requires more force to overcome its friction.
If I understand the question correctly: It is actually ill-posed. The frictions you are refering to are dynamic (sliding) and static (starting). I think you will find that static friction is always harder to over come than dynamic friction, not vice-versa.
Starting, or static, friction is greater than sliding friction in general. Static friction requires force to be overcome as the object rests on a surface due to its roughness. The roughness is a bunch of small contact points under high stress that resists motion; once this resistance is overcome, the object moves and its velocity allows the surface to glide over the rough spots more easily . This sliding friction is thus a little lower than static friction
True -It's "False"!
FRICTION
Sliding Static Fluid Rolling
Sliding friction is the force impeding movement as a result of two surfaces rubbing against one another. Imagine pushing a cardboard box of books across a concrete garage floor. Rolling friction refers to the frictional forces between a rolling tire and the pavement. The tire gets warm and an inflated tire rolls easier. The sliding friction is much more difficult to overcome than rolling friction.
The force that prevents two forces in contact from sliding past each other is friction. Friction has the ability to keep things from moving.
Static friction is stronger than sliding friction because it prevents an object from starting to move, while sliding friction resists the motion of an object in contact with another surface. Rolling friction is typically the weakest of the three, as it only occurs when an object is already in motion, and the friction forces are reduced due to rolling instead of sliding.
Friction prevents surfaces in contact from sliding past each other. There are several types of friction including dry friction, fluid friction, lubricated friction, skin friction and internal friction.
