Newton found that the apple fell from the tree and practiced writing 200 words.

Newton, a teenager, found that the apple fell to the ground. Newton,164212 was born in a farmer's family in Woolsop village, Lincolnshire, England on February 25th. /kloc-When he was 0/2 years old, when he was studying in a public school in Grantham, he showed great interest in experiments and mechanical inventions, and made water clocks, windmills and sundials by himself. It was accidental that the apple fell to the ground and caught his attention. One hot noon, little Newton was resting on his mother's farm. Just then, a ripe apple fell. The apple hit Newton right on the head. Newton thought, why didn't the apple run and fall? He asked his mother, but she could not explain. Most scientists keep a childlike innocence, and Newton is no exception. When he grew up to be a physicist, he thought of the story of "the apple fell to the ground", which may be that some force on the earth attracted the apple to the ground. So Newton discovered gravity.

2. Profile of people

Sir isaac newton (1643 65438+1October 4th-1727 March 3rd1), chairman of the Royal Society, a famous British physicist, is an encyclopedic "all-rounder" and author of Mathematical Principles of Natural Philosophy and Optics.

He described gravity and three laws of motion in the paper "Laws of Nature" published by 1687. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering. By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the movements of ground objects and celestial bodies all follow the same natural law; It provides strong theoretical support for the sun-centered theory and promotes the scientific revolution.
