General Planar Motion
See also: Polar coordinate system (section: vector calculus)The previous equations for planar motion can be used here: corollaries of momentum, angular momentum etc. can immediately follow by applying the above definitions. For any object moving in any path in a plane,
the following general results apply to the particle.
Kinematics  Dynamics 

Position  
Velocity

Momentum
Angular momenta 
Acceleration

The centripetal force is
where again m is the mass moment, and the coriolis force is The Coriolis acceleration and force can also be written:

Famous quotes containing the words general and/or motion:
“We raised a simple prayer
Before we left the spot,
That in the general mowing
That place might be forgot;
Or if not all so favored,
Obtain such grace of hours
That none should mow the grass there
While so confused with flowers.”
—Robert Frost (1874–1963)
“A movement is only composed of people moving. To feel its warmth and motion around us is the end as well as the means.”
—Gloria Steinem (b. 1934)
