Friction is the force that can make sliding difficult, as it opposes the motion of two surfaces sliding against each other.
It takes more force to make a stationary object start sliding because you need to overcome the static friction between the object and the surface. Once an object is already sliding, it requires less force to keep it moving due to kinetic friction, which is typically lower than static friction.
The force of friction for a sliding object does not typically vary with speed, as long as the sliding conditions remain the same. Frictional force is more dependent on factors like the roughness of the surfaces in contact, the normal force pressing the surfaces together, and the coefficient of friction between the surfaces.
You would have to overcome sliding friction to make a book move across a desk. Sliding friction is the force that resists the motion of two surfaces sliding against each other.
It may seem harder to start sliding a couch because of the friction between the couch and the floor. The weight and size of the couch can make it more difficult to overcome this friction and get it moving.
Work = Force x Distance Friction is a force usually operating in the opposite direction to the force being applied. Thus friction adds to the size of the force applied and work is increased.

When you walk it requires a force which is reacted by the floor in opposite direction. With zero friction it is difficult to make any forward progress as no force is reacted, so you cannot walk but will slip.You can try to put foot down always normal to the floor, and you make some progress, but mostly you will be sliding, not walking.

You have to kill your way into it. sometimes they force you and make you choose to either be with them if not they kill you

shoes...that make you slide...
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.
The opposing force to the effort force is called the resistance force. This force acts in the opposite direction of the effort force and can make it more difficult to move an object. The relationship between the effort force and the resistance force determines the overall motion of the object.
The geography of Mesopotamia made it a difficult place to live because sometimes it would rain and because it was had a lot of hills
