Isaac Newton discovered gravity when an apple fell on his head. He then began to think about how the apple had fallen on his head and this is how Newton's three laws of motion were created. Newton's first law of motion is that an object in motion tends to stay in motion; an object at rest tends to remain at rest unless another force is exerted on it. Newton's second law of motion concerns the force formula, which is force = mass * acceleration. Newton's third law of motion states that for every action, there is an equal and opposite reaction. Additionally, Isaac Newton created the three laws of motion. First, Newton's first law of motion is that an object tends to stay in the state it is in unless another force acts on it. This law is also known as the law of inertia. When an object is moving, it would like to continue moving forever, but in reality it stops. It stops due to various reasons such as air, the surface it is traveling on, gravity and it may hit an obstacle. This is why, in space, any object would continue to move indefinitely, because nothing stops it from moving....
