• Teacher's Manual Included
• Adjustable String Length
• Students Learn How Different Factors Affect a Pendulum's Period

Users can adjust string length and the mass of the pendulum. A large protractor makes angle measurements easy to read, and the photogate system can be attached at the bottom of the swing arc to record the period.

Students can investigate how the angle of release, mass, and string length affect the period of a pendulum.

The FUN stand and fundamentals of physics photogate system are required, but available separately.

This kit includes a protractor backboard, string, pendulum bob and weights, mounting screw, and activity guide.
