Circular motion and radial forces

What this note covers

1. Velocity changes on a circle even at constant speed
2. Connect period, frequency and speed
3. Resolve real forces into radial and other components
4. Analyse vertical circles at specific positions
5. Understand release, work and direction
6. Investigate the radial-force relationship
7. Worked vertical loop: force equations change with position
8. Worked turn design: friction supplies a radial net force
