... To set an object in motion, a force has to be exerted on it. Kinematics is the study of objects which are already in motion, disregarding the force that caused the motion in the first place. A study of the forces will be considered in Chapter 3. To describe the motion of an object, we need to specif ...

... Q10.25. Reason: Assuming the woman raises the weight at constant velocity, the force she exerts must equal the weight of the object. Since the mass of the object is 20 kg, its weight is about w mg (20 kg)(9.80 m/s2 ) 200 N. Since she lifts it 2 m, the work done is W Fd (200 N)(2 m) 400 ...

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.
