... Two kinds of non-conservative forces: Applied forces: Forces that are external to the system. These forces can take away or add energy to the system. So the mechanical energy of the system is no longer conserved. If you were to carry around a ball, the force you apply to the ball is external to the ...

While you gently hold the block in place, have a partner pull the board out from under the block so the block slides along the strip, not across – don’t rip the strips.

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
