Physics Classroom Demonstration Board for Force Composition and Decomposition with Magnetic Mount and Clear Center Panel Display Use Multicolor

Features: Physics Force Demonstration: Use this magnetic parallelogram law board to show force composition and decomposition in a clearer way during classroom explanations, guided practice, and lab discussions. Magnetic Mounting Design: The magnetic mounting design helps teachers place the demonstrator board on a metal board fast, reducing lesson interruption before vector demonstrations begin. Clear Observation Layout: A metal backboard with a transparent acrylic panel keeps the string layout visible, helping learners follow direction changes and force relationships during instruction. Two Gauge Teaching Structure: Two force gauges with strings form a ready-to-show demonstration layout, helping instructors compare vector relationships during physics lessons and mechanics topics. Classroom Ready Set: The demonstrator measures about 35cm/13.8inch x 40cm/15.7inch and includes 1 set for classroom or lab use, with a streamlined structure that supports routine lesson preparation. Specifications: Component: Metal Plate + Acrylic Panel Size: Approx.35x40cm/13.78x15.75inch Quantity: 1 Set Package Includes: 1 Set Magnetic Parallelogram Law Demonstrator note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you donot mind before you order. 2.Due to the differences between different monitors, the picture may not reflect the actual color of the item.
