United Scientific Maxwell’s Wheel measuring 12-1/2 in L x 5-1/2 in W x 18 in H is a classic device and features metal construction for enhanced durability. It is designed to demonstrate the conservation of mechanical energy as well as its conversion from one form to another. The wheel is rotated to roll the supporting cords to the top by hand and then released. The potential energy of wheel turns into kinetic energy of rotation as it falls. Wheel reaches bottom position when it rolls the cords up again, the kinetic energy changes back to potential energy. Process continues until all the energy is lost to friction. It comes with activity guide.Includes: Activity Guide Shipping Details Shipping Type: parcel Free Shipping: true Specifications Allergens: Contains No Allergens Certifications: Not Applicable Grade Level: Middle-High School Specialty Shops: Clearance SUOM Description: Each Brand Name: United Scientific Description: Maxwell’s Wheel California Proposition 65 Warning: WARNING: iWARNING: This product can expose you to chemicals including Lead, which is known to the State of California to cause cancer.
