Durable inclined plane for forces, motion, and energy investigations Make simple machines and motion studies clear, repeatable, and student-friendly. Arbor Scientific’s Inclined Plane is a versatile, heavy-duty apparatus designed for investigating forces, motion, and energy with minimal experimental error. With a 100 cm long, 13.5 cm wide track, it easily accommodates cars, balls, blocks, and masses for a wide range of classroom investigations. The inclined plane attaches easily to a stand (not included) and adjusts to virtually any height, allowing students to explore how angle affects motion and force. A precision pulley and roller assembly at the top supports equilibrium and force-balance experiments, while the sturdy construction ensures reliable performance through years of classroom use. Why Teachers Love the Inclined Plane Versatile and adjustable: Quickly changes height and angle to support many different experiments. Designed for accurate data: Precision pulley and roller assembly help minimize friction-related errors. Built to last: Sturdy powder-coated steel construction stands up to heavy, repeated student use. Wide working surface: Accommodates a variety of carts, blocks, balls, and masses without crowding.
