<\/span><\/h2>\nOne of Newton’s most important contributions was the formulation of the law of universal gravitation. According to this law, every particle of matter in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Simply put, the force of gravity between two objects decreases as the distance between them increases.<\/p>\n
Applying this law to Earth, Newton determined that the gravitational force acting on an object near or on Earth’s surface could be calculated using a specific value for the acceleration due to gravity, denoted as g<\/b>. He estimated Earth’s gravitational acceleration to be approximately 32 feet per second squared (32 ft\/s\u00b2).<\/p>\n
This value of g<\/b> is crucial, as it allows us to quantify the strength of gravity pulling objects towards Earth, enabling us to predict and understand the physical behavior of objects in our everyday lives.<\/p>\n
