No.
Some of it is lost as friction.
Kenetic energy would be converted to friction, which, in turn, would be converted into heat and sound energy. (Imagine a train as it screeches to a stop.)
Not directly; the two are independent. But if an object with gravitational potential energy falls, that energy may be converted to kinetic energy.
