... • Speed is the distance traveled divided by the time taken to travel the distance • Formula: Speed = distance ÷ time (S=D/T) • SI Unit: meters per second (m/s) • Ex. In the 100m dash the fastest runner finished in 10s. S= 100m/10s= 10m/s • 3 Types of Speed – Average speed is found by dividing the to ...

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.
