If you can treat red rice note3 as a mouse, what experiment would you like to do?
Find a bouncy ball. The size of the ball is irrelevant. The key is to be elastic and make a certain sound when playing. Then turn on the phyphox on the mobile phone and turn on the "elastic collision", then put the mobile phone near the ball, let the microphone on the mobile phone receive the sound when the ball bounces, and click the record button to release the ball. In the whole process, the number and time of dropping the ball will be recorded, and then the bouncing height of the ball can be calculated by using the time interval between two drops. Of course, the experimental site is generally in the gravity environment of the earth, and the acceleration value is 9.8 m/s2.
