Intro to 1D Kinematics with Physlets
Twelfth graders examine illustrations and animations on a Physlets CD in which they must describe motion, analyze graphs, and calculate initial velocity. The Physlet assists in providing active class participation in discussion.
Curated OER
Accelerated Frames of Reference: Inertial Forces
Students examine how when applying the laws of motion to an object in an accelerating frame, using coordinates defined in such frame, one must always add an "inertial force", representing forces caused by the frame's acceleration.
Curated OER
Looking into Eratosthenes' Radius of the Earth
Students, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of the...
