PSWORKSTM Conservation of Energy Tracks
Learn about kinetic energy using these curving conservation of energy tracks! Will the track with the steep incline produce a ball with more kinetic energy than the straight track? This activity illustrates that the kinetic energy of a ball at the bottom of a track is directly related to the potential energy it had at the top. When a ball drops a certain distance, it always has the same kinetic energy no matter what path it took to the bottom. PSWORKSTM Support Stand, or equivalent, is required.
PSWORKSTM Lever Arm
Illustrate the concepts of balance and rota- tional motion with this 60-cm lever arm. Experiment with first-, second- and third- class levers. The Flinn PSWORKSTM Lever Arm attaches to the PSWORKS Support Stand, not included. Additional materials needed are weight hangers, weights and string.

PSWORKSTM Pendulum
Demonstrate simple harmonic motion and the conservation of energy with this large pendulum. The string length and the mass can be changed to affect the period. Two pendulum bobs are provided. PSWORKSTM Support Stand is required, but not included. Photogate Timer is recommended to measure the period of the pendulum or the speed of the pendulum bob.
AP7000 | $51.40
PSWORKSTM Parabola
Convince your students that a projectile follows a parabolic path! Launch a ball bearing using the unique launching mechanism, and watch the ball skim the surface of the track. Flipping the parabola over coverts it to a conservation of energy track. Made from durable hardwood—it will last for years! Teacher instructions and student worksheet are provided. PSWORKSTM Stand, or equivalent, is required.
