This complete set includes

 

This set is used to demonstrate the resolution of forces on an inclined plane, uniform and accelerated motions, kinetic and potential energies, and the friction between two surfaces.

 

The wooden inclined board is 60cm long and 10 cm wide. It can be set at any angle between 0 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 componants of the force exerted by the plane.  The aluminum wheel and cone bearings on the Hall’s carriage help minimize friction on the inclined plane.  Activity Guide and complete instructions included.
