Affordable, Easy, Fun
Present these demonstrations in front of your class to excite your students about learning core physics concepts. Set up and execution are simple, so you can spend more time engaging your students. Ideal for introducing a unit or using as reinforcement after a lesson, these demos are available for all fundamental physical science topics.
Two 70 cm long spring scales allow students to easily see and demonstrate force experiments and equilibrium. When a mass is hung midway between the two springs it causes equal displacement in each spring. If the mass is hung off–center, the two springs are elongated different distances. Displacement measurements can be easily assessed using the metric scale on the tube. Includes two large spring scales, a connecting rope with hook, and a fully–detailed demonstration guide. Each spring has a constant of approximately 78 N/m. Masses are not included.
