Let us take a closer look at exactly what the force of gravity is and how it affects the human body, both on the ground and during flight. The multitude of satellites currently orbiting our planet provide a constant reminder of the accuracy and applicability of Newton’s Laws. The fact that heavier-than-air aircraft can travel with intention to and from various points on earth, suspended in the Earth’s atmosphere demonstrates our current understanding and manipulation of gravitational forces. The basis of these laws and our current understanding of Newtonian gravity are integral to many technologies today. The development of Newton’s three laws of motion further explained the general behavior of forces and more specifically the way in which gravity behaves. …and so it was that the mysterious force of gravity was revealed to Isaac Newton and the human mind for the first time.įrom observing and contemplating that everyday occurrence of a ripened apple falling from a tree, the young Isaac Newton began to understand (and later to mathematically demonstrate) one of the four fundamental forces of nature.
Why should that apple always descend perpendicularly to the ground, thought he to himself.” 1 It was occasion’d by the fall of an apple, as he sat in contemplative mood. “ After dinner, the weather being warm, we went into the garden and drank thea, under the shade of some apple trees…he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind.
