Newton had been asked to address the question of why planets move as they do. He established that a force of attraction toward the Sun becomes weaker in proportion to the square of the distance from the Sun.
His contributions changed the way we see and understand the world around us.
Less than 50 years before Isaac Newton was born it was thought that the planets were held in place by an invisible shield. Isaac proved that they were held in place by the sun’s gravity. He also showed that the force of gravity was affected by distance and by mass. He was not the first to understand that the orbit of a planet was not circular, but more elongated, like an oval. What he did was to explain how it worked.
He brings to science new ideas. He put forward planets held in place by the sun’s gravity, showed that the force of gravity was affected by distance and by mass and so on.
