NEWTON'S 3RD LAW
Young scholars examine the formal definition of Newton's 3rd law: "forces always originate in pairs, equal in magnitude and opposite in direction." --The informal, qualitative version: "Each action has an equal and opposite reaction."
Curated OER
MOTION IN A CIRCLE
Young scholars 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.
