Eisco Labs Rolling Friction Halls Carriages (Cars), Includes 4 Cars With Different Wheel Types

• Kit contains 4 cars, instructions, it is recommended you gather washers or something to vary mass
• Wheels are mead of: Wood, Fabric, Soft Rubber, Silicone
• By setting the cars in motion with equivalent velocities the user can qualitatively demonstrate the frictional properties of rolling without slipping.
• Instruction manual included

The rolling friction car kit provides four cars for exploration into the force of friction. Each car provides a set of different material wheels (wood, fabric, soft rubber, soft silicone) with a different coefficient of friction. By setting the cars in motion with equivalent velocities, one can qualitatively demonstrate the frictional properties of rolling without slipping
