With its metal construction and a rectangular wooden base measuring 40 x 10 cm, it provides a stable base for observing motion while keeping the setup compact enough for a desk or teaching table. As a centrifugal force demonstration, the model uses a slanted metal track, two circular loop sections, and a small metal ball to show how movement changes along the course. Watching the ball travel through the loop track model helps students connect physical motion with basic physics ideas in a simple, graphic manner. The teaching model is supported by a frame that holds the track in place, making the structure easy to inspect from different angles. Its overall height of 33 cm gives the model a noticeable presence, which makes it useful for home school lessons, science activities, and guided demonstrations where learners benefit from seeing each part of the path clearly. Because the model combines a roller coaster form with a straightforward demonstration layout, it is well suited for repeated observation and discussion. It offers an engaging way to examine force, speed, and track design through direct experiment rather than abstract principles exclusively.","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/d566bf2e-43f3-45a0-8358-7f846fda0ac9.jpg?v=1787392511","href":"/product/wp-dcd-10001229776.html","buy_url":"https://uecyem-u1.myshopify.com/products/wp-dcd-10001229776","buy_url_source":"shops.shop_domain + product.handle","seller_name":"uecyem-u1.myshopify.com","seller_url":"https://uecyem-u1.myshopify.com/","return_policy_url":"https://uecyem-u1.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/d566bf2e-43f3-45a0-8358-7f846fda0ac9.jpg?v=1787392511","alt":null,"position":0}],"related":[{"handle":"ladies-fashion-earrings-0-10ct-round-diamond-10k-yellow-gold-2","title":"LADIES FASHION EARRINGS 0.10CT ROUND DIAMOND 10K YELLOW GOLD","category":"Curated goods","price":"$299.99","image_url":"https://cdn.shopify.com/s/files/1/0013/1655/2764/files/361966Y-5012795_b97ef613-4426-400c-90cf-90f16b99dd31.jpg?v=1789310493","sku":"361966Y","href":"/product/ladies-fashion-earrings-0-10ct-round-diamond-10k-yellow-gold-2.html"},{"handle":"paani®-grip-sleeve","title":"Paani® - Grip Sleeve","category":"Bottling Bottles","price":"$15.00","image_url":"https://cdn.shopify.com/s/files/1/0618/9996/4598/files/FRONT_900ML.jpg?v=1764945364","sku":"5065018111440","href":"/product/paani-grip-sleeve.html"},{"handle":"10k-white-gold-double-heart-diamond-pendant-for-ladies-0-15ct-round-diamond-pendant-with-chain","title":"10K WHITE GOLD DOUBLE HEART DIAMOND PENDANT FOR LADIES 0.15CT ROUND DIAMOND PENDANT WITH CHAIN","category":"Curated goods","price":"$449.99","image_url":"https://cdn.shopify.com/s/files/1/0013/1655/2764/files/361947W-5012778_773c4969-f14f-4f3a-a499-ddca0ac7c354.jpg?v=1789310489","sku":"361947W","href":"/product/10k-white-gold-double-heart-diamond-pendant-for-ladies-0-15ct-round-diamond-pendant-with-chain.html"},{"handle":"ladies-ring-0-50ct-round-diamond-10k-yellow-gold-6","title":"LADIES RING 0.50CT ROUND DIAMOND 10K YELLOW GOLD","category":"Curated goods","price":"$1049.99","image_url":"https://cdn.shopify.com/s/files/1/0013/1655/2764/files/348223Y-4946115.jpg?v=1789310486","sku":"348223Y","href":"/product/ladies-ring-0-50ct-round-diamond-10k-yellow-gold-6.html"}]}}
