Inquiry question: Why do objects move in circles?
Students:
● 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 (ACSPH100)
● solve problems, model and make quantitative predictions about objects executing uniform circular motion in a variety of situations, using the following relationships:
● investigate the relationship between the total energy and work done on an object executing uniform circular motion
● investigate the relationship between the rotation of mechanical systems and the applied torque
