# Alvl P2: circular motion (ch10) Cheat Sheet by MostAncientDream

aqa A-level physics year 2 (yr13) circular motion : chapter 10

### circular motion

 a force moving in a circular experi­ences a centri­petal force that acts towards the direction of axis of rotation F = mv2/r velocity is a tangent to the force at a point - constant speed but always changing directions - therefore there is a variable accele­ration

### angular velocity

 w = angular veloci­ty/­fre­que­ncy­/speed in rads-1 v = (2pi/T)r = (2pi f)r therfore v = wr

### loops

 for vertical loops: you have a circle A- left furthest side B- highest point C- right furthest side D- bottom when travel­ling- at A/C > support force = mv2/r B > mv2/r - mg D > mv2/r + mg banked planes­/banded tracks: mv2/r = mgtan0 to try and visualise- -plane coming towards you -angled towards the left the the right wing face towards the sky -there is mg downwards -centr­ipetal to the left (axis of rotation) - there is a force u angled up the the diagonal left at 0 degrees to the normal
