Question

Why does a moving object come to a stop on a frictional surface?

Answer 1

The energy is posses has converted into heat energy and sound energy

Answer 2

So in other words, you can say that it's kinetic energy has been converted into the other two aforementioned energy, thus, it's velocity decreases slowly to zero as the formula of energy states that kinetic energy = 1/2mv^2

Answer 3

because the force of friction acts as a anti-force of the force that moves the object and the kinetic energy of that object is converted into heat, some of the energy is lost transited into the surface as well
