Find the effective value of g due to height |
|
Answer» a = G*M/R², where a is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance, which, at sea level, the average radius of the Earth is 6.376 * 10^6 m. For a height h, the acceleration due to gravity is: a = GM/(R+h)^2 … so it decreases as h grows. Explanation:What you need to notice about these equations -The strength of Earth’s gravitational field on a body gets weaker as you move FARTHER away from the Earth’s center. Gravity is considered a weak force. -Because of the magnitude (10^6) of these variables, h MAKES LITTLE DIFFERENCE until it too, is a sizable number. Thank you ! |
