Connect circular-motion kinematics with the real forces that produce radial acceleration. This 33-page resource contains 24 questions, with six conceptual multiple-choice questions and problems graded from Foundation through Extension. Fully worked solutions explain the method, show intermediate steps and calculations, and interpret the answers. Covers angular quantities, radial dynamics, friction, conical pendulums, banked curves and vertical circles. Curriculum and university-bridge extensions are labelled. Includes linked questions and solutions and a separate instructor question map. Part of the Phi Advanced STEM Studies Premium Mechanics Series.
