Answer: Scientists viewed the laws of nature in the past as something that wasn't stated, nowadays we are sure about them due to years of investigation. The Law of Universal Gravitation State connects with apples falling and planets circling in orbit because he hypothesized that gravity is not limited to Earth. The three main things that Newton was known for are; inertia, force, and action and reaction.
Explanation: Back in the day, there wasn't proof of natural laws; therefore, every scientist that disagreed with a hypothesis, presented his own. Nowadays, after centuries of knowledge, we believe in the stated laws.
The Law of Universal Gravitation State connects with apples falling and planets circling in orbit because Newton hypothesized that gravity is not limited to Earth, but that there is a force of attraction between all material bodies. Then, all the planets follow their orbits.
The three main things that Newton was known for were his three laws; The first law stated that if a body is at rest or moving at a constant speed in a straight line, it will remain like that unless force is used to move it. This is called inertia. His second law states that a force applied to a body can change the magnitude of the momentum or its direction. The third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. It is known as the law of action and reaction.
