... Stress the reasoning behind each equation, for example, that velocity is a ratio that describes a property of objects in motion. Likewise, acceleration is a time rate of change of velocity, so vf - vi/t not only makes sense but can be reasoned out rather than memorized. Also stress the need to show ...

Conservation of Mechanical Energy
... The conservation of energy says that the kinetic energy at the bottom of the drop will equal the gravitational potential energy at the top. KE = PE ½ mv2 = mgh Divide both sides by m to get: ½ v2 = gh Then multiply both sides by 2 to get: v2 = 2gh Take the square root of both sides to get: v = √2gh ...

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.
