Dynamics
... If a force acts of a body, the body will accelerate. The ratio of the applied force to the resulting acceleration is the inertia (or mass) of the body. If a torque acts on a body that can rotate freely about some axis, the body will undergo an angular acceleration. The ratio of the applied torque to ...

Concept Summary
... o Acceleration changes the velocity (in magnitude, direction, or both). o Acceleration can speed you up or slow you down (often called deceleration). o Constant velocity means the acceleration is zero and visa versa. o Average acceleration = change in velocity/elapsed time vector quantity = magnit ...

... For an object of constant mass over time, its acceleration a is proportional to the force F and inversely proportional to the mass m of the object. a = F/m. If the mass changes over time, the more general statement of the law is F = d(mv)/dt = ma + (dm/dt)v. ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
