Wool Cloth for Electrostatic Charging Item Type_Density Cubes & Cylinders Designed to measure Planck's constant

Designed to measure Planck's constant through the photoelectric effect

Steel U-section 170cm track on foot supports

Demonstrates that horizontal velocity is independent of vertical motion by ejecting a ball vertically from a moving aluminum car

holding under at least 100 Newtons of separation force after hand-evacuation of the air between them

Wool Cloth for Electrostatic Charging Item Type_Density Cubes & Cylinders Designed to measure Planck's constantUsed to generate triboelectric static charge by rubbing against glass, rubber, or acrylic rods, this wool cloth is a standard accessory for electroscope and Van de Graaff work.
