Friction
... gravity (on earth) is 9.8 m/s/s. (in this example we will round it to 10m/s/s). Acceleration is determined by dividing force by mass. As you see the two objects if dropped at the same time, from the same height will accelerate to earth at the same speed and hit the ground at the same time. An object ...

Model of a Bicycle from Handling Qualities Considerations
... The second is a torsional spring. The greater is, the greater the moment felt as resistance to rotation. In our case, MFf-SA does depend on , and the relationship is linear in . But MFf-SA depends also on many other variables, including the bike’s speed, the wheelbase, the head-tube angle, etc. ...

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.
