Posted on January 1, 2011 by Arbor ScientificChapter 25 Lab #68: Students will build a pendulum with a period of one second.
Posted on January 1, 2011 by Arbor ScientificStudents first measure the vertical displacement of a pendulum bob and calculate its potential energy compared to equilibrium. The predict the pendulum bob's maximum velocity and then measure the actual velocity at the bottom of the swing.
Posted on January 1, 2011 by Paul RobinsonThe Flying Pig provides students with a fun way to study circular motion. The pig and its string trace a conical pendulum and allow a perfect opportunity for calculations and measurements of circular motion. Students should be familiar with forces, specifically centripetal force, and how it is calculated. Students should also know the definitions of the fundamental trigonometric functions and how they can be used to find the sizes of parts of a right triangle.
Posted on January 1, 2011 by Arbor ScientificThe Bouncing Dart is a specially designed pendulum with one elastic end and one inelastic end. Students will collide each end with a massive (1kg or more) cart, observing the pendulum's motion and measuring the distance the cart moves. They will conclude that elastic collisions transfer more momentum.

Posted on January 1, 2011 by Arbor ScientificTwo experiments. Choose one. In the first, students are guided through the process of testing 3 variables; mass, length, and amplitude; to determine which affects the frequency of a simple pendulum. In the second, students use inquiry and experimental design to test the same variables.
Posted on January 1, 2011 by Arbor ScientificA pendulum with its mass spread throughout its length is called a physical pendulum. A typical clock pendulum is an example. Students will observe a physical pendulum and measure its period, and then construct a simple pendulum with the same period. They will see that a physical pendulum acts as if its mass is concentrated at its center of mass.
