Have you noticed the position of the hole in the first two spinners? Did this difference in the position of the hole make a difference in the spinning of these spinners?
Yes, the position of the hole makes a significant difference in spinning. When the hole is at the centre, the spinner appears the same from all sides and remains upright while spinning smoothly. When the hole is away from the centre, the spinner becomes unbalanced because the weight is not distributed equally around the pivot point. This causes the spinner to wobble and not spin properly.
Explanation
The chapter explicitly states: 'In the table of Activity 2, the first spinner with a hole at the centre appears to be the same from all sides. This spinner remains upright and spins but that is not the case with the second spinner.' This demonstrates that central positioning of the pivot point is essential for balanced spinning motion.
