Regents Exam Prep Center: Interactive Games and Puzzles for Algebra 2 & Trig
This educational resource consists of interactive games and puzzles that investigate algebra and trigonometry concepts. Some concepts included are functions, quadratics, and trigonometric graphs. [Requires Java Plugin.]
Khan Academy
Khan Academy: Trig and Forces: The Pendulum
Using Newton's Laws of motion to calculate the acceleration of a pendulum as well as to compute and draw its position along the swing and move about the screen in a computationally based graphic system.
Texas Instruments
Texas Instruments: Swinging Along
Students model the data from the motion of a pendulum by a periodic function. They relate its parameters to the time for one period, the distance it is pulled back, and its distance from the motion detector.
