The force that slows down moving objects is friction, the action of two objects rubbing against each other. This scenario illustrates the action of Newton's Second Law.
the force is called gravity (I'm not really sure if that's the right answer, but you can just go to google and type in force that slows down moving objects, glad if I helped(:
Unbalanced , because as long as it is moving it is accelerating therefor it is unbalanced . Now if it is at a complete rest then it is not accelerating therefor it would be a balanced force .
That is called friction.
Yes, Sliding friction opposes the movement of the book, slowing it down.
Friction is a force that always opposes motion. The force of friction therefore slows down the sliding object.
Newton's first law states that every object that is moving will continue moving at constant speed in a straight line until an unbalanced force acts upon it. An object at rest will remain at rest until an unbalanced force acts upon it. A golf ball remains at rest until the unbalanced force of a golf club. Then, it will continue moving at constant speed until an unbaleced force acts on it. What slows it down is friction. Then, the hole or wall will stop it.
friction stops things from moving and slows it down
sliding friction slows down a sliding object
friction or drag
because after the object is moving, and the forces are balanced, the force trying to slow it down (like friction, or air resistance) is equil to the one moving it, so it neither speeds up nor slows down. the same applies to the force trying to move the object.
Friction? Air resistance?
Presumably you mean friction.
Static friction and sliding friction. Static friction is the force that stops a mass from sliding and sliding friction is the force that slows down an object that is already sliding. Static friction is stronger than sliding friction, and this difference is reflected in different coefficients of friction for sliding and static friction for a given surface.
Static friction is the force that must be overcome in order to initiate the object's motion, ie. to start the object moving. Sliding, or Kinetic (moving) friction is the force that resists the object's motion , ie. it slows the object down if it's already moving. Generally, Static friction is a higher value than kinetic friction, ie. pushing an already moving object is easier than pushing a still object
