Product Description Product DescriptionConcave and convex bridge demonstration deviceProduct Introduction According to the requirements of the "Standards for Equipping High School Science Teaching Instruments" issued by the Ministry of Education in 2010, I The company has developed a concave convex bridge demonstrator. This instrument consists of two parallel concave convex tracks, a bracket, steel balls, and track clearance adjusters. main Used to demonstrate the forces exerted on moving objects on concave convex bridges.Experimental steps: 1. Place the steel ball at the lowest point of the concave bridge and adjust the gap adjuster until the steel ball is gently adjusted with your fingersThe position that falls off easily upon touch. 2. Roll the steel ball down from the starting point position, and then see that when the steel ball reaches the lower part of the concave bridge, it falls under the track I went. This phenomenon indicates that due to the upward direction of centripetal force, the track provides greater support for the steel ball Gravity means that the pressure of the steel ball on the track is greater than its own gravity, so it falls below the track. 3. Reduce the gap between the concave bridge to prevent the steel ball from falling during the descent process, and place the steel ball between the upper and lower sections of the concave bridge Adjust the gap adjuster to a position where it can fall off with a gentle touch of your finger. 4. Roll the steel ball down from the highest point and see it passing through the concave and convex bridges to reach the end pointSet. Why doesn't the steel ball fall off the track when passing through the convex bridge? This is because when passing through the highest point of the convex bridge Downward in the direction of centripetal force, the support force of the track on the steel ball is less than that of gravity, which means that the steel ball on the track The pressure is less than gravity, so it can pass through without falling below the orbit. Attention: This instrument should be handled with care during use to avoid damage. After use, put it back in its original place Store in a cool and dry place properly in the packaging.
