Friction Apparatus

Versatile Unit Tests Several Factors of Friction

• Investigate the affect of weight on frictional forces
• Includes an Activity Guide

This set includes a friction block and a friction board, both made of high quality, smoothly finished pine wood. The friction block has a hook for a spring scale and two compartments for additional weights. It can be placed face-up or sideways. Students can vary the weight or area of contact to see how they impact the friction force. It also includes three 50 g weights, a 100 g spring scale, and a comprehensive activity manual. The board is 20" x 2" and the block is 4" x 1 1/2" x 1".
