Curated OER
MOTION IN A CIRCLE
High schoolers explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T, and the "centripetal acceleration" of an object.

Motion in a Circle
Students study about deriving centripetal acceleration for motion at constant speed around a circle.
Curated OER
Motion in a Circle
Students explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T. They examine how uniform circular motion is a type of accelerated motion.
