... Now, the amount of a physical quantity remains the same, no matter what system of units is used to obtain a numerical measure of that quantity. For instance, we might measure the length of an (American) football field with a meter stick and a yard stick. We’d get two different numerical values, but ...

... A friction force between two objects in contact opposes the sliding of one object over the surface of the adjacent one. It is tangent to the surface of the adjacent object and opposite in direction to the velocity of the moving object. The magnitude of the frictional force is assumed to be proportio ...

Part 1 - How Things Work
... (according to Newton's Second Law of Motion): for the wheel-less wagon to accelerate to a stop to decelerate, it needs a net force acting on it in the direction opposite its velocity. What could possibly be exerting that force? The answer is friction. In addition to its downward weight, a gravitatio ...

... In each example, the object has one position at which the net force on it is zero. At that position, the object is in equilibrium. Whenever the object is pulled away from its equilibrium position, the net force on the system becomes nonzero and pulls the object back toward equilibrium. If the 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.
