centripetal

centripetal         
  • Upper panel: Ball on a banked circular track moving with constant speed ''v''; Lower panel: Forces on the ball
  • A body experiencing [[uniform circular motion]] requires a centripetal force, towards the axis as shown, to maintain its circular path.
  • Vector relationships for uniform circular motion; vector '''Ω''' representing the rotation is normal to the plane of the orbit with polarity determined by the [[right-hand rule]] and magnitude ''dθ'' /''dt''.
  • Local coordinate system for planar motion on a curve. Two different positions are shown for distances ''s'' and ''s'' + ''ds'' along the curve. At each position ''s'', unit vector '''u'''<sub>n</sub> points along the outward normal to the curve and unit vector '''u'''<sub>t</sub> is tangential to the path. The radius of curvature of the path is ρ as found from the rate of rotation of the tangent to the curve with respect to arc length, and is the radius of the [[osculating circle]] at position ''s''. The unit circle on the left shows the rotation of the unit vectors with ''s''.
  • Velocity and acceleration for nonuniform circular motion: the velocity vector is tangential to the orbit, but the acceleration vector is not radially inward because of its tangential component '''a'''<sub>θ</sub> that increases the rate of rotation: ''dω'' / ''dt'' = {{!}} '''a'''<sub>''θ''</sub>{{!}} / ''R''.
  • Polar unit vectors at two times ''t'' and ''t'' + ''dt'' for a particle with trajectory '''r''' ( ''t'' ); on the left the unit vectors '''u'''<sub>ρ</sub> and '''u'''<sub>θ</sub> at the two times are moved so their tails all meet, and are shown to trace an arc of a unit radius circle. Their rotation in time ''dt'' is ''d''θ, just the same angle as the rotation of the trajectory '''r''' ( ''t'' ).
