The apple discovered by Newton fell from the tree 200 words of shorthand pen practice

1. Story

When Newton was a boy, he found an apple falling to the ground. Newton was born on December 25, 1642 in a peasant family in the village of Woolsthorpe, Lincolnshire, England. When he was studying in Grantham's public school at the age of 12, he showed a strong interest in experiments and mechanical inventions, and made water clocks, windmills and sundials by himself. It was by chance that the apple fell to the ground and caught his attention. One hot noon, little Newton was resting on his mother's farm. At this moment, a ripe apple fell. The apple hit Newton on the head impartially. Newton thought: Why doesn't the apple run up but fall down? He asked his mother, but her mother couldn't explain. All scientists retain a childlike innocence, and Newton is no exception. When he grew up and became a physicist, he thought of the boy's story of "the apple falling to the ground." It may be that some force on the earth attracted the apple to fall. Thus, Newton discovered universal gravitation.

2. Character introduction

Sir Isaac Newton (January 4, 1643 - March 31, 1727), President of the Royal Society, and a famous British physicist Scientist, encyclopedic "all-rounder", author of "Mathematical Principles of Natural Philosophy" and "Optics".

In his paper "Laws of Nature" published in 1687, he described universal gravitation and the three laws of motion. These descriptions established the scientific view of the physical world for the next three centuries and became the foundation of modern engineering. By demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravity, he showed that the motions of ground objects and celestial bodies follow the same natural laws; he provided strong theoretical support for the heliocentric theory and promoted the Scientific revolution.
