Newton`s First Law
... NOTE: MASS and WEIGHT are NOT the same thing. MASS never changes When an object moves to a different planet. What is the weight of an 85.3-kg person on earth? On Mars (g=3.2 m/s/s)? ...

Newton`s First Law of Motion
... Newton’s first law is often called the law of inertia. Every object continues in its state of rest, or of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted upon it. ...

Multiple Choice:
... 1. No, the speed does not change. The force is perpendicular to the velocity and so only the direction of the velocity changes, not the magnitude. The force is centripetal. 2. While it is true that the acceleration due to gravity is dependent upon distance from the center of the earth, and so does t ...

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.
