Tutorial_Putty Collision
... When we set the momentum before the collision equal to the momentum of the system after the collision, there will not be other variables in our relation between the speeds, because we know that mA=mB=m. Note: In general, this problem can be solved for spheres with different masses. This problem is a ...

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.
