Friction between the ball and the floor is stealing some of the kinetic energy of the ball, and turning it into heat.
Answer:
As atoms in the spoon vibrates about their equilibrium positions and transfer energy form one end to other end. This process is called conduction.

Work is the force on the object as it changes a distance. Interestingly, as work is done on an object, potential energy can be stored in that object. For example, if you carry a load up the stairs. Now that load will have potential energy that can be transformed into kinetic energy and so on
If you search that click the first link ;)
Yes an object in motion has kinetic energy
