Circular Motion
This activity is a TI-Nspire simulation for students exploring uniform circular motion and its implications on a moving particle. Students first make observations regarding the tangential velocity of the particle, and then use a measurement tool to confirm that the magnitude is constant while the angle between the initial and final velocity vectors is constantly changing.  An further simulation allows students to determine the relationship between the radius of the orbit and the straight line displacement of the particle. Using this information, students can derive the general equation for centripetal acceleration. Teacher notes and student question are included as a pdf file.Â
This resource will allow students to actively investigate the physical features of uniform circular motion and determine a larger relationship between the radius of the circle and the speed of the object. Students are able to visualize the dynamics of the UCM situation and vary certain properties, resulting in a greater understanding of the overall relationships and final equation for centripetal acceleration.
