Major steps for analyzing forces in uniform circular motion: Let consider one axis along the radius of circle (i.e. in direction of acceleration) and other axis perpendicular to the radius. Resolution all the forces into horizontal and vertical components.
Net force along perpendicular axis=zero
Total force along radial axis (towards centre) =mv2/r=mω2r
Triangle of force Two or more forces can be added or subtracted to produce a Resultant Force . If two forces are equal but act in opposite directions, then obviously they can
