Explore the area of applicability of the mathematical pendulum. To do this, change the length of the pendulum’s thread and the dimensions of the body. Check if the period of oscillation depends on the length of the pendulum if the body is large and the length of the thread is small.
if the body is large and the length of the thread is small, then the pendulum is not mathematical. The longer the thread length, the longer the oscillation period.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
