At the highest point without falling, continue to roll along the track to another inclined track and move into the bag.\u003c\/li\u003e\n\u003cli\u003e* Repeat to make the ball roll down the ramp several times, but gradually reduce the height of the starting point, it can be seen that when it is less than a certain value, the ball can not reach and pass the highest point of the circular orbit, but from close to the highest point A certain point of the point deviates from the track and makes an oblique upward throwing motion, and its curved path deviates into the ring, and finally falls on the track below.\u003c\/li\u003e\n\u003cli\u003e*Result: Only when the speed of the ball passing the highest point of the circular orbit is equal to or greater than a certain value, the centripetal force required for its circular motion is equal to or greater than the gravity it receives. The resultant force of the ball can be exactly the centripetal force, so it can be smooth Pass the highest point of the track.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47666911739988,"sku":"SPH-B0G1SVNZWT","price":60.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/31EelAnfgRL._AC_SL1500.jpg?v=1789309935","url":"https:\/\/learnbrightminds.com\/products\/b0g1svnzwt","provider":"BrightMinds","version":"1.0","type":"link"}
