Physics Question Newton's 3rd Law?
- Steve4PhysicsLv 71 month ago
The force on Gemini 9 ('G' for short) is the gravitational attraction of the earth. This force causes G to have an orbit (rather than simply moving away in a straight line).
Newton's 3rd law tells us there is an equal magnitude force on the earth(earth attracted by G). However, the earth's inertia (mass) is so large the resulting motion of the earth is too small to measure.
