About this item:
This set is used to demonstrate the resolution of forces on an inclined plane, uniform and accelerated motions, kinetic and potential energies, 
and friction between two surfaces. The wooden inclined board is 60cm long and 10cm wide. It can be set at any angle between 0 degrees and 45 degrees. 
The two scales on the protractor allow angle measurements to be made directly or by trigonometry.
Students can determine the coefficients of static and sliding friction and verify the normal and frictional components of the force exerted by the plane. 
The aluminum wheel and cone bearings on Hall's carriage help minimize friction on the inclined plane. Includes activity guide.
