WebMay 24, 2024 · We can set that equal to the equation above, and solve for a, the acceleration due to Earth's gravity: a = G M E / R E 2. where M E is the mass of the Earth and R E is its radius. We know the values of all these numbers: G = 6.672 x 10 -11 N m 2 /kg 2. M E = 5.96 x 10 24 kg. R E = 6375 km. WebJan 21, 2024 · English mathematician Sir Isaac Newton was the first to explain gravity in a way that applied to all objects, as we know it today. But Newton's explanation was not the whole story - and actually drew together many ideas that scientists and philosophers had been musing over for centuries before him. In the 300s BC, Ancient Greek philosopher ... graphtec free software
