CHAPtER 2 Collisions and other interactions
... When two or more objects collide, the change in the motion of each object can be described by Newton’s Second Law of Motion. By expressing Newton’s ∆p second law in the form Fnet = , it is possible to examine the effect of col ∆t lisions on the human body. When a car collides with an ‘immovable’ ob ...

... Many of those candidates who first considered only the car omitted the tension and so did not see the need for a second equation. Quite a few elementary arithmetic mistakes were seen. Often done better than part (i). Quite a few candidates used wrong exotic methods to find the tension. The dynamics ...

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.
