Useful For Exploring The Concept Of Motion On An Inclined Surface And Its Relation To The Friction. A Pair Of Polished Wooden Boards Attached Together At Each End Are Hinged At One End To A Metal Baseboard Below It So That The Wooden Boards Can Be Moved To Form An Inclined Surface. One Side Of The Board Has A Linear Scale Graduated Every 5Cm To Measure Linear Distance Along Its Length, While An Adjustable And Removable Arc Scale Graduated 0-45°X1° Measures Its Angle Of Inclition. Angle Measure Also Has Linear Scale Graduated In Centimeters To Measure The Vertical Height Of Inclined Surface At A Point. A Plastic Pulley Attached To The Inclined Boards Supports Masses Suspended From Thread, The Other End Of Thread Being Connected To The Object Moving On Inclined Surface.
