... Another important idea is the work energy theorem. It states that the work done by the net force acting on an object equals the change in Kinetic Energy of the object. Work = ∆ Kinetic Energy Since Work is defined to be Force multiplied by the distance an object moves in the force’s direction, the w ...

... From the information given in the problem we have m = 5, b = 10, and v0 = 50. Also g = 9.81. Substituting these values in the above formula and simplifying give the equation of motion: y(t) = 4.905t + 22.5475(1 – e –2t). To answer the remaining question, transform the question to determining when th ...

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.
