📚Syllabus
● Conduct investigations to explain and evaluate, for objects executing uniform circular motion, the relationships that exist between:
– centripetal force
– mass
– speed
– radius
● Analyse the forces acting on an object executing uniform circular motion in a variety of situations, for example:
– cars moving around horizontal circular bends
– a mass on a string
– objects on banked tracks
● Solve problems, model and make quantitative predictions about objects executing uniform circular motion in a variety of situations

What is circular motion? What is centripetal force? What is centripetal acceleration? Linear vs angular speed.

There's a mistake at 14:46 - the radius should be 2 m, not 5 m. This would give you a speed of 62.8 m/s.
