Physics 11 - Notes
... When objects freefall (stones, rocks, balls, or any falling object) they always have the same acceleration. In reality there may be other forces but for us we are dealing with only acceleration due to gravity, which is a constant near the earth's surface, of -9.8m/s2. If you move further away from t ...

Answer: This is the mathematical expression for the equilibrium rule, which states that the vector sum of the forces acting on an object is equal to zero if that object is in a state of rest, or a state of unchanging velocity. "Vector sum" means that direction is vital. If for example, an object is ...

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.
