	A [[force]] is a critical influence on motion. Some forces visibly change the speed or direction of motion. Other forces convert macroscopic motion to microscopic motion. A '''non-conservative force''' is the classification given to any force whose [[work]] is dependent on the path taken because microscopic effects are dependent on macroscopic phenomena.

Some forces visibly change the speed or direction of motion. Other forces convert macroscopic motion to microscopic motion. A '''non-conservative force''' is the classification given to any force whose [[work]] is dependent on the path taken because microscopic effects are dependent on macroscopic phenomena. In short, a non-conservative force converts macroscopic motion into microscopic motion.

	*'''[[Normal force]]:''' ~~When~~ a baseball bat ~~hits a baseball~~ (macroscopic motion)~~, the hit~~ will make a sound (microscopic motion), see ~~figure~~ 1.		*'''[[Normal force]]:''' The collision between a baseball and a bat (macroscopic motion) will make a sound (microscopic motion), see Figure 1.
	*'''[[Air drag]]:''' After a baseball player hits the baseball, the ball ~~moves~~ through the air (macroscopic motion). The ball will make ~~the molecules in the air~~ vibrate ~~faster—creating~~ heat (microscopic motion). This is the same as the [[mechanical equivalent of heat]], which converts motion of a [[fluid]] to [[heat]]. The more air drag there is, the faster the ball will dissipate energy.		*'''[[Air drag]]:''' After a baseball player hits the baseball, the ball will move through the air (macroscopic motion). The ball will impart [[kinetic energy]] on air molecules and make them vibrate faster. This creates heat (microscopic motion). This is the same as the [[mechanical equivalent of heat]], which converts motion of a [[fluid]] to [[heat]]. The more air drag there is, the faster the ball will dissipate kinetic energy into thermal energy.
	*'''[[Friction]]:''' When the player slides to the base (macroscopic motion), friction will ~~cause the atoms in~~ the ground ~~to shake more,~~ the player's pants ~~move~~ more~~, and make sound~~ (microscopic motion).		*'''[[Friction]]:''' When the player slides to the base (macroscopic motion), friction will impart energy into the ground and the player's pants. This causes the atoms in the ground to vibrate more (microscopic motion) and may even cause plastic deformation (like stretching or tearing the pants) that can be further losses of kinetic energy.

	All real systems have some non-conservative forces associated with them. For example, when the moon rotates around the Earth it creates [[tidal force]]s, which will warm the [[ocean]]s ~~slightly~~. However, it's a small effect compared to the energy in the system.		All real systems have some non-conservative forces associated with them.
