How is gravity calculated? |
|
Answer» We can do this quite simply by using Newton's equation: forcegravity = G × M × mseparation2 . Suppose: your MASS, m, is 60 kilogram; the mass of your COLLEAGUE, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 -11 newton square METRE kilogram-2. |
