Features
• Watch the movement of the steel ball on a vertical circular orbit and analyze the motion conditions of the steel ball at the highest point of the circular orbit.
• Care should be taken to protect the steel ball during the test, and do not let it fall to prevent damage.
• Scientifically explore experimental supporting instruments
Description
Place the track on the desk, level the base, and then roll the ball from the highest point on the ramp from the standstill. You can see that the ball can smoothly pass the highest point of the circular rail in the vertical plane. Do not fall, continue on another ramp that rolls along the track and move into the bag. Repeat the ball several times from the ramp, but gradually reduce the height of the starting point, you can see 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 the highest point At a certain point, the track is lifted off and the obliquely throwing motion is performed. The curved path is deflected into the ring and finally falls on the lower track. Only when the velocity of the ball passing through the highest point of the circular orbit is equal to or greater than a certain value, the centripetal force required for its sensitive circular motion is equal to or greater than the gravity it receives, and the resultant force of the ball can be used as a centripetal force so that it can smoothly pass the orbit. The highest point.
