WebMay 6, 2015 · Assume the arrow is 1m long, and the reference altitude is 400km. Acceleration due to gravity is µ / r 2; Earth's µ (standard gravitational parameter 3 /s 2, and radius is 6371 km. Figuring for altitude of 400km and 400.001km (these values added to the planet's radius), the difference in acceleration is about 0.000002568 m/s 2-- that's 2.6 … WebJan 8, 2014 · Gravity is a force, so it just provides one way for objects to exchange and transform energy to different states. If I lift a bowling ball to the top of a hill and let it go, the ball falls, speeds up, and seems to gain energy. Isn't this a case of gravity giving energy to the bowling ball? No.
