... A car of mass m=2000 kg coasts down a hill inclined at an angle of 30o below the horizontal. The car is acted on by three forces; (i) the normal force; (ii) a force due to air resistance (F=1000 N); (iii) the force of weight. Find work done by each force, and the total work done on the car as it tr ...

Force and Motion in Two Dimensions - juan-roldan
... An object’s acceleration is usually parallel to the slope. One axis, usually the x-axis, should be in that direction. The y-axis is perpendicular to the x-axis and perpendicular to the surface of the slope. With these coordinate systems, you have two forces—the normal force and the frictional force. ...

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.
