Circle of Forceless Motion The Upward Acceleration Caused by The Combined Force of Gravity and Supporting Force On an Object Concave-Convex Bridge Demonstrator

Description

Take a steel ball and place it at the bottom of the concave bridge. Adjust the distance between the iron wires at the hip of the two bridges so that the iron ball just does not fall when it is stationary. Apply a little pressure with your fingers, and the ball will open the bridge arms and fall. Then, let the ball roll down the inclined arm. You can see that when the ball reaches the center of the bottom of the concave bridge, it falls from between the wires of the bridge arm. This shows that the pressure of the moving ball on the bottom of the concave bridge is greater than the pressure at rest. This is not difficult to explain, because when the ball passes through the center of the concave bridge, the combined force of gravity and supporting force on the ball produces upward acceleration. It can be seen from N-mg=mv"/R that if v≠0, then N) mg.
